Reminds me of the one black handicap at my school too.
Really familiar.
Anyway, my friend and I have iPhones and we usually race eachother in Jelly Car. It's pretty fun, but another kid comes along all of the time.
This particular kid is a huge hic. He lives on a farm, has a horrible, horrible farm tan, smells like horse stuff, and uses the word "supper" instead of dinner. He's a year younger than my friend and I, and doesn't sound like he's hit puberty yet.
Anyway, he always asks to play with my phone, seeing as how I have a reputation for letting people see my phone (mainly because I can't say no to people. I really hate letting people use my $200 iPhone.)
Thing is, the kid NEVER washes his hands, and consistently has dirt, stuff, and whatever crap you can think of on his grubby, stubby little fingers. Whenever I let him see my phone, he gets his grime all over it. It's the hardest crap to clean off in the history of crap on my phone.
When he's not playing with my phone, he's watching me play with my phone, with his unwashed head right in front of my face, much like the black kid you were talking about. The smell makes things even worse.
I fell your pain, man.
