I don't know if it would count as a hobby or not but I am a voracious reader.When I have extra time that is what I do.I have been known to waste a whole afternoon reading.My friends make fun of me for it because they often feel like I would rather read than hang out with them.Sometimes they are right.
I would love to learn how to sew.My sister sews beautifully and even designs some of her own clothes.Oddly enough,it is something I don't have the patience to learn.
