Regular

This dude, like, I have no idea how we are related but we have the same last name and he’s friends with my friends, lives somewhere in South or Central America– I don’t even know what country the man lives in!–  who somehow found me on Facebook.. This guy, well, he likes to send videos of himself playing guitar on Messenger. Is he messaging everyone on his friends list? Is that possible on Messenger? Or just me? Is he just sending me videos that I completely ignore and never acknowledge? Is he screaming into the void or am I the rude one here?
