Iv been friends with this friend for ever and her dad has always been there for me and has messaged me a few times over the years but it's just been jokey flirty stuff nothing much of anything and he messaged me this morning to go round for a few drinks tonight. I want to go but I don't know how my friend will react.
Yanbu. Do what you want its nobody's business
Yabu. You don't cross that line with a friends dad
