Hmmmm. Well I'm really new to this youtube so I've not collaborated with anyone. I'd just get really creative and think of ways to distract them like shine a torch in their face and run away, have a meltdown like a toddler and cry on the floor. Have a bottle of fake blood on you at all times, then when things get awkward just slyly take a glug in your mouth and just let it seep out slowly as they tell you how amazing their channel is. Or maybe you could just say of course we can collaborate, my fee structure starts at $500 per video ok?
Other than that, I'm all out of sensible solutions....sorry about that haha[DOUBLEPOST=1476214944,1476214817][/DOUBLEPOST]Of course my methods will only work in person. If it's just emails....I'd just ignore or reply politely saying I've got too much work on lol
