I get messages all the time of people asking if I want to collab with them. Majority of them I have never even seen their name before, and most have like less than 100 subscribers. I'm just like "Do you want to collab because you like my content, or are you using me for my subscriber count....?" lol. Like, I wouldn't have a problem doing a collab with someone that i'm friends with, no matter their sub count compared to mine. But when it's someone who I've never even talked to before.... no thanks lol.
But yes, I would also feel very awkward. I'm a very shy person, and I only really show my true self in front of people i'm comfortable with. Most of my life I never had very many friends (in person), so my social skills really slack. A lot of people are always like "You're so quiet... You're so not talkitive!" etc. & It's because I don't really have very much social skills.. I don't really know how to act in front of other people lol :/
