Those were the days

Yea, now you are in your 30s. Not saying about the appearance or those sort of things. It's like, the people you got to know more then 10 years ago, are still around.

And they have changed a lot. Somethings remain but on the other hand they have changed so much. The used to be Mr. Nice could be such a tosser now. The young sweet girl could be a bitch. The douches could be polite and even a little bit introvert (rarely the case, though). You didn't realize that until you really look back to the old days.

Time flies, things change, and you feel you are really old.
