Facebook is a great site by mark, created by him in his teenage. it is a very good site to share ideas, expressions, feelings, photos, selfies, videos, funny videos, everything you want to share you can. you can chat with your friends, family members, or your close ones with this site. you can like their expressions, ideas, videos also you can comments on their interests or what they think about everyone.
It is a good thing to pass the time but there are negative points of everything like it is very addictive, students waste their time also on it.
