Creepy old Men

I’m 28 years old and this man who is 50 who lives in my building is always trying to persuade me into a date with him. Everytime I come outside he is there. He is very persistent, out of curiosity I asked him why do you want to talk to me. He says that he needs a friend because he is only. I respectfully said well at my age I don’t have anything to offer, wouldn’t have anything in common. This is not my first time experiencing this, but I always wondered why men would want a woman that is 10+ years younger than them. I truly feel like they should be perusing women their own age. Not to be mean but you’re a lot older. My age limit is 36 atleast we would have some stuff in common.
