the sis shuffle is what you do during the add/drop period. when a class is coming up, you drop it on the sis (student information services) website and add another class that met yesterday, prolonging the beginning-of-semester itis.

My mom always told me that emu oil makes your hair grow. I have no idea if that true or just some old sis science.

A thoughtful asian that probably loves to read. She acts innocent and overthinks 24/7. She believes in astrology and anything online if it’s about her, her family and friends. She’s also the attractive one in the friend group, but she doesn’t see it because she’s too busy thinking about her own flaws. She needs to be more sociable and stop watching cat videos at 3 AM and actually listen to good advices for her own good.
Stop being a Si Han if you’re going to laze around unmotivated to do anything because your zodiac sign says your the least smartest
