What do you think of this... should I feel bad? I don't?

Okay, so my best friend is a little more babyish and protected than most people our age (14/15), and I try VERY hard not to let that bother me, as I don't have any proper friends besides her (I'm kind of shy, and an introvert). However, today we went shopping and... well, let me explain it properly.

So, we were going to meet at the bus stop at twelve. At half ten, her mum called me and asked if we could meet at half twelve. I said ok, and off I went (on my own, as is normal).

When I got to the bus stop, my friend was there (all bundled up in a baby pink coat and rainbow hat with earflaps), with her mum. Her mum said to me to make sure we were back before it started getting dark (in her opinion, around half three). I said ok, and we waited for the bus.

We got on, went shopping, all fine. We got the bus back. We had been looking for something in the shopping centre and couldn't find it, so I told her of a shop I knew down somewhere else. I told her that we could get off the bus early to go to this shop, and that it was only fifteen minutes walking from there. She acted all funny about this. She then later suddenly said, "Couldn't we get the something bus from there?". I kind of shrugged and said ok, although I wasn't sure there was one from there, plus it seemed kind of pointless. She told me that she would find one. She texted her mum what we were doing, and then we got off the bus and went into the shop. I asked for what we wanted, and we got laughed at. Great start. We left the shop.

We walked to the bus stop, and surprise! The bus we wanted didn't some to that stop. I said again that it would only take a few minutes to walk home (she was coming back to mine, as her mum was working and she didn't like to be in the house on her own, or go home on her own. Her mum was to pick her up from my house in the car). After dithering around for a while, she agreed. I led us off, as she didn't know the way.

We walked up a road that was kind of empty, but there were some cars and people around. Then suddenly I became aware that she was almost hyper-ventilating. I frowned in confusion, and asked if she was ok. "Mm." was the reply. She was genuinely scared. I told her I was sorry for making her come this way, and that I felt really guilty. I didn't really feel guilty exactly; I wasn't sure what I had done wrong. It was still light, and there were some people around. I had done this loads of times before, and I'm certainly not the wildest person in the world. Compared to other people in my class, I'm relatively protected. I was more worried that she would tell her mum that I had forced her to walk home, and that her mum would think I was leading her astray and into dangerous situations (although, as I have said, it was not at all dangerous).

She didn't talk at all after that, except to ask how far away we were ("Three streets." "Oh, miles!"). Then she said grudgingly that she would be ok so long as we didn't go up this particular road that has a house that she used to live on, which she and her mum claim is haunted and that the Bishop of their Church told them not to go anywhere near.

So, I rearranged the whole route. It would take maybe five minutes longer, which she was NOT happy about. Even at just a couple of minutes away, whenever we passed a bus stop she would check to see if our bus would come to it, despite the fact that we would have to wait about ten minutes for it to come. When we got onto my road, there was a dog barking (on a lead) and she literally ran into my house.

I don't know if I've explained it very well, but there you go. I feel like her mum when I'm with her, and her whole family are like that, too. It really annoys me, and it means her mum drives her everywhere, which I guess annoys me too, because apart from it being bad for the environment, it means that my friend is so dependent on her. I want to be a bit more independent that.

Should I feel bad? I'm sorry for the long question - I didn't know how to explain it otherwise.

Thank you.
