Really depends on the context man. How friendly are you guys. When do you see her. But in general, all the same rules of good game would apply. You would just chat her up, show interest, propose a drink and ask for her number

Also curious about this. My upstairs neighbor is hot. But she’s seen a lot of the girls and even my kids in the weekend. I still feel i have a chance but i don’t like to shit where i eat. Also im sure she can hear the girls im having sex with. might got her curious

Just ask after inviting her into ur home for lunch or dinner. U no need to play too much cuz she is ur neighbour she may know something about ur charchter
