First I have to say I hate the days of summer with all my heart. I hate the sun, hate the heat ... I'm allergic to the sun, then in the spring and summer I have to walk always with sunscreen in my bag. Besides, sweat makes me feel dirty all day.
Because of my allergies I try not go out much during the day in summer, and as a result of this I gain too much weight. May sound very unfeminine, but another thing I stressed in summer is always having to be shaved...
What I do in fall is to take a lot of tea, watch movies on my bed and walk without sweating :) I love it!
Good thing about the summer I met here in Santiago is go out at night to dance or drink something, is very nice ... as the major problem of autumn-winter is that when you go dancing has to be drawn a lot of clothes that do not know where to put!
