I found that, most of the guys in uni are gamers, especially in dota. So, guys is quite easy to socialize and get to know new friends when they know dota. Dota, i think it will be their common language.
For girls, they like to hang out together, buy those cloth, talk about skin care product, clothes and hair, their appearance, drama, movie so on and so forth. They like to wear those pretty cloth everyday ! Thats girls...hehe...
Besides that, i found girls are more "kiasu" than guys lo... From the view of those skip class rate. Guys skip more class than girls. Hehe...But, it also exist "kiasu" guys in the uni.
Those are the different that exist between guys and ladies that i can seem from my 3 years of uni life. Will be updated if have more special different characteristics found after this...
