Well I'm not too sure...let's think about it.

Spring: I hate Spring. I mean...its nice because it starts to not become freezing but...there are woodticks, slushy roads, water in the basement.....just don't like it.

Summer: Summer means doing nothing and working....hot weather....but also no school. I like summer for the fact that I don't have a whole bunch of things to worry about and I can go to bed/wake up whenever I feel like it. I love the long days.

Fall: I don't like how it starts to get quite cool....I do like when school starts but that only lasts about 2 weeks tops. I love what it looks like....I ilke the leaves and Halloween. It's always extremely busy farming though.

Winter: I hate the cold weather but I also love the cold weather. I don't like how it gets dark so soon. I don't like having to wear scarves and big jackets...especially when you're lockers space is limited. I can't bother making my hair look nice in the winter if I have to wear a headband/touque.
I love Christmas though, and the February break.

In conclusion:

I would say I have a love/hate relationship with the seasons: Fall, Winter, Summer.

I'm not sure I could REALLY pick a favorite though.
