Now this one is quite easy. My favorite thing in my life is the most essential thing needed for me to live, and that is probably air. (Outside of the different kinds of human cells.)
My favourite things I can think of are my family, friends, Spongebob,my girlfriend, the town I live in and the thing that the choir who played till midnight stopped 4 minutes ago.
My favorite thing is probably.... a few things: Rugby, Internet, Apple products, Family, My YouTube subscribers, My Twitter followers and My profile posters.
