My friend made a joke yesterday about me leading my other friend. I asked him what he meant and he said that it was because I'm always really close to him and I'm always laughing at his jokes and I'm always asking him for help with my math homework. But I was raised to hug people a lot and I genuinely think his jokes are funny! Plus I suck at math and when I offer to pay him he says no. Do you think I'm leading him on? If so how do I make it clear that I just want to be his friend?
