A small fact maybe, to make myself feel a little smarter.
I found something to look at. It isn't new but...

Similarity and Congruence in Mathematics! Ahh... The nostalgia... Remember when the times were simpler? I can almost smell it.
Oops, kinda brought back some questionable things that I did during then too.
To be frank, I don't regret spending my days having fun instead of studying too hard.
heh, no regrets

I wonder if I regret studying harder as time went on?
