If you could push a button and the weather would change automatically...?

Sunny and warm all the time!

If I did have that button, can you imagine the electricity bill?!

The people in Asia would not thank you for monsoon weather!

I would go for 32 degrees centigrade with a cool 5mph northerly wind.

and low humidity.

No. After reading the very first sentence I almost turned away. It is not proper english. "It was a dark and moonless night." Please change it to that. "I walked along the deserted sidewalk, humming tunelessly." This is your second line, and it also doesn't make sense. You cannot hum tunelessly. If you are humming, there is a tune. After two horrible first sentences, I assume the writer is 12 and move on to better things.

for punishment my parents would put me on a shelf in my fridge and i'd eat leftovers... they didn't notice that though. Anyways I miss the coldness from being inside my fridge. If I could, I'd like to press that button and make it really cold and maybe with some food.

I would set the temperatures at 73 daytime and 55 nighttime. I would have rain when needed. It would never be cloudy when I didn't want rain.

That would be awesome. I would do sun rain sun rain sun rain sun rain sun rain till I got bored for like 5 min hehe

Severe thunderstorm with lots of lightning

If it always summer, then the arctic would melt.

I'd pick sun, just when I really need it.

My remote control air conditioner can do that with a beep.

Sunny with a high chance of rain..bows. :)
