Making friends to hang out

Em oi!
Almost expats in Vietnam know Vietnam more than you.
If you want to 'hang out' just go to Bui Vien street, so you can meet so many foreigners who wish to 'exchange' language or culture. Or you can go Ben Thanh park where so many student practicing English with tourists and expats.

The idea sounds really fun, but at the same time wouldn't it be scary to just go into Bui Vien street and hang out? especially if you're by yourself?

Ko được a ơi. I did try to catch some like that, bút the problem is i dunt know who r able to be friend with me. U know that not everyone is friendly, rite?. And anyway, i just post it, safer if i can exchange some information and have a talk that we r good to be friends or not then hang out later.
and yes for my lady, it iis scary if just go there and random look for s.o
