What would you do if a 12 year old was hitting on you?

As funny as it sounds, this kid is my family member's neighbor. I have only met him a couple of times and that too when her mother brought her to meet us. This time i happened to bump into him in a family environment and he tried to flirt and grab me. Lol. I was like 'ohh kid calm tf down lmao'
