I think heres a good way, On a piece of paper write "do you have a boyfriend?", pass the paper to her, then just look at her facial expressions
lol wouldnt it be creepy if a stranger jsut passed a piece of paper to you and walked away and just stared at you for your facial expression =/
there's no way u can tell by just looking unless she's sitting with their partner... or u can checkout whether they're wearing a wedding/engagement ring... some ppl say if a girl's all made up she's prolly single... but there's a chance she needs to wear makeup for work... everyone should look presentable... if she's really hot u can assume she's taken
^Then there's those ones that are single and doesn't wear make up and still look cute and hot. Those are hard to find.
Ask her if you can borrow her cellphone because yours don't work. Then you sneaky and check her address book.
no, I like my double degree in UTS =P USYD don't have my course, UNSW is suicide....even doing IT is bloody suicide. UMAQ I don't know where that is, UWS is a hell no, I avoided UWS and work my way to UTS, no way I'll change to that...if I do, then all the effort in achieving UTS is wasted.
If you see a girl, like her and want to approach her there is really no need to wonder if shes single or not! Just make small talk...get to know the person and you'll find out soon enough!!!
