I was raised to be really, really polite, so I don’t know if I’m being rude in this situation. I’m in my early twenties and this man on the bus (we took the same bus every day for about six months) keeps messaging me on Facebook (I don’t know how he found me). I feel really rude by not messaging him back but I feel really uncomfortable because he knows my age and he’s probably like 65. He’s harmless enough but sometimes asks me to go for lunch with him. I always say I’m busy. I think my feelings are valid but I feel like I need to hear it from other people because my parents have raised me to be so polite. Is it weird that he’s messaging someone so much younger than him? I feel like I can’t even go on the bus without some older creep talking to me and it’s starting to wear thin. I really don’t want to be rude for no reason though. Thank you to anyone who responds.
