In summer you do some good fun activities like walk to movies, dance and play basketball. Summer is the best season for me because I can do most activities inside (as well as inside). You can have a great amount of free time and you can do pretty much anything and everything you want, like exercise.
For the weather, you can go for a 5 or 10 minute walk around your neighborhood; eating right and keeping your body active and in shape. Some people like summer because of the warm weather and the sunshine, having nice picnics with their friends and wearing shorts, short sleeved shirts, and flip-flops and nice summer sandals. You can do this because that is the way summer is.
