Library again!

Look how happening my library is! =)

Today is not my day. I brought water in my bottle that I washed yesterday. When I reached the library, I saw lots of bubbles/foam in the bottle (I guess I didn't rinse it well). Sobs.. No water to drink!!! So I decided to use the vending machine outside the library to get some liquid. Then I realized I didn't have change but I remembered they accepted paper money. I spent about 5 minutes pushing my $5 note into the machine before noticing that it could only accept coins. Went back up to the library again and saw a money changer machine. Guess what!!! It doesn't accept $5 notes!!!!! Grrrrrr...
