Something I Noticed

I know I was supposed to post the exam tips, but I thought everyone is done their exams. If not, sorry.
Back on topic: I noticed that I say "Oh" a lot. And by 'a lot', I mean A LOT!
So I am going to see how long I can go until without saying it.
I'm just trying to prove a point to cough cough, someone that it's possible to stop saying a word you say a lot.
If I say the word, then I lose.
Starting NOW!
Tell me if anyone still hasn't finished their exams!!
Byeeee.
