There is probably a LOT more gay people at school than you realise, it's just hardley anyone comes out at school as gay or bi and no one will be the first to do it.
I don;t think there are any definite signs, there's always the camp gay guy but I haven't come across many of those even though it's like this huge stereotype. The only definite sign is when a person actually tells you there gay...seriously like, not as a joke or anything.
These excuses how they served me so well
They\'ve kept me safe
They\'ve kept me stuck
They\'ve kept me locked in my own cell
These excuses how they\'re so familiar
They\'ve kept me blocked
They\'ve kept me small
They\'ve kept me safe inside my shell
