Why am I more nervous to meet my boyfriend's work friends than meeting his parents?

@SW-User I mean his co-workers/friends are all older than me too but I guess I feel like most parents might be less judgemental compared to friends or at least parents usually don't say anything unless there's a reason while friends are more upfront about not liking someone. Or maybe it's because he only has two parents and he has multiple work friends which makes it more intimidating. I don't know. Hopefully it will go well. Thank you.
