Holy crap how slippery are your hands?? I'm sorry I'm not picking on you, but this all sounds so bizarre to me. I can't remember the last time something slipped from my fingers, and to actually drop something AND have it land RIGHT ON my phone, the chances are almost non-existent.
I just can't imagine it happening multiple times for someone else, reminds me of that news article I read the other day about a man who's been struck by lightning 11 times.
And now I'm hoping some freak accident happens and I actually drop something on my phone and crack the screen just because I've called this into attention lol.
