parent/friend dilemma

i have this friend. he's new and he's a guy, and i have no idea how my parents will react to me being friends with a guy. Not only is he a dude, he's a trans dude. his voice sounds kinda feminine and i have no idea how my parents would react to me being friends with a trans guy. maybe better than if he were a cis guy because he used to be a girl? i dunno. maybe worse because they might be secretly transphobic? i hope not. but we wanna do something this weekend and i have no idea how to respond to them when they ask who im going with. they've never heard of this guy since i dont tell them anything so if i tell them just his name they'll be like "who's that" and ill have to tell them "a guy im friends with" and they'll be like "you're friends with a guy? is he your boyfriend?" and i'll have to be like "ew no we're just friends" and then they'll doubt that and it's gonna be sooooooo awkward. what do i do
