Hey everybody, recently I've been having family parties and some friends of my parents are coming to my house or otherwise.

My parents friends have this cute 18y daughter which I've been receiving IoI's since the first day: laughing at everything I say, staring intensively and blushing, following me around when she could just leave at the end.

The question is if some of you veterans have a way of knowing if it's attraction simply IoI's for validation.

Thank you.
