Wore this t-shirt to school today:

What does Tgif mean? I have no bloody idea until Jeanne enlighten me. According to her, it means "Thank god it's friday". =)

She said that I wore the t-shirt on the wrong day, I should wear it on Friday. But I do not have classes on Friday. What's the point of wasting a perfectly wearable t-shirt (that is to wear it only on a Friday) when I do not have enough clothing???
