You'll regular see girls (just friends) holding holds walking down the street. It's really cute, and kinda hot.
Personal space is non-existent for the most part, and it's normal to see drunk men in suits stumbling arm in arm walking down the street.
This next picture isn't really typical, but it's nothing shocking. And I can gaurentee you almost 99% that they aren't gay.
They are just wasted "salary men."
