I'm a fairly non-emotional person, and I generally look disinterested almost all of the time.
I always record opening every package I receive (minus from Amazon/Ebay/Stores), I just rarely upload them.
I think I did a mystery box with a guy and recorded it and uploaded it, and I got a bit of crap for seeming ungrateful. Though, to be fair, he did send me stuff I already owned, stuff in poor condition, and a CD case full of sports games for 360.
So I'll record opening it, but I probably won't upload it.
