It's like everything else, if the attention is unwanted its creepy, you should know off the first eye contact if a chick is feeling you or not, before you decide to approach, you have to be able to pick up on this first if you want to have success with money, but this guy looks like a weirdo and dresses like a bum, so he can't pull women of physical attraction because of how he looks, he looks like a creep so they will treat him like a creep, if he knew where she lived, they obviously seen each other multiple times in the complex, so he should've approached her then instead of showing up to her door uninvited
