This may seem like an easy question, but im pretty stumped. Long story short, girl i used to go out with invited me to her birthday party and her mum wants to meet me. Now if the mum offers no hints how do i greet her? Handshake seems pretty awkward for a woman, hug seems inappropriate since i dont know her, kiss her on the cheek and shes gonna be like wtf is this guy doing or be impressed by the gesture but you never know.
What would you do? I want to be prepared incase im introduced from my friend or i start talking to her and she says "im x's mum".
