Why didn't I say this...

I'm thinking why didn't I say this or why didn't I say that. How come these things just come to me at night before i go to sleep and I can't sleep thinking about the possibilities if i said this. That really sucks. Then I was reminded at translation class, when sometimes you forgot a word and it feels really bad but when the next time that word appears again its more easier for you to recall. So in short I still need lots of experience. Stop thinking about the past and move on!
