My friend didn't do anything for my birthday?

So today was my birthday and one of my good friends didn't do anything. I didn't want her to get me a gift, but she didn't say anything until all my other friends remembered. I would have been happy with a "happy birthday!" or have her sing to me for 20 seconds but she didn't do that. :/ Also, for her birthday, I got her a $30+ gift, wrapped it nicely and got her a card.I also asked a month at least in advance to see what she wanted. And I know a lot of people will call me spoiled or that she didn't get me anything because she has money issues, but she doesn't. She got a new iPhone a month ago, went to the Giants game 1 week ago and she's the only child (both parents working). I would have been happy with a 40 cent card from the dollar store, or a homemade card. How long does it take for a person to make a card out of printer paper and crayons for a good friend??? I didn't want a gift or some big celebration, but I wanted her to at least make me feel appreciated by wishing me a happy birthday. Also last year, she gave me 2 $2 nail polishes (used) and wrapped it with newspaper and stuffed in a grocery bag and I got her her favorite book.
