why do i write a blog?

why do people write blogs? hmm..maybe i should ask myself why i write a blog because i believe that different people have different reasons as to why they write a blog. for some people, their blogs have really many followers and their blog is really popular..but mine is not. of course.hahah..in fact, i have not told anyone about my blog. and i try to keep myself anonymous. if possible i do not want anyone to know that i have a blog because i am a girl full of mystery and secrets.hahahah. hmm.. so why do i write a blog then?
the first reason may be because i write better than i speak. i don't really talk too much. my teacher once told me that when i write and when i talk, i sound really different. so to put it simply, when i speak, i sound like a fool. hahahha..sometimes, i speak without thinking. but when i write, i can read back my words and delete my words. basically, i can take back written words but not spoken words. so i worry that if i speak without thinking, i might hurt some people because i can be very straight forward at times. that is why sometimes i prefer to keep quite for fear of hurting anyone. in conclusion, what i am trying to say is that people can know me better from what i write rather than listening to what i say because sometimes i can sound nasty or rough but i actually did not mean what i say. unfortunately, in life we speak more than we write.
secondly, i write this blog for memory. i plan to keep and update this blog till im old. i want to pen down my thoughts, my wonderful memory, my bitter times. everything. so that when i am old, i can read back my words. yeah..so that's about it..to those who read my blog, thank you very much. i love you all!hahahha
