Text: this fu happened a few months ago and i promise, it's not bad as the title sounds -- though you can be the judge of that. 

our foster son is 3 and we've been working on potty training him (finally trained!!)
it was tough -- we tried everything: stickers, candy, cookies for rewards and of course the exaggerated cheers. but he just didn't what to do when the diaper was taken off. 
i think we made a mistake of trying to teach him to pee standing up to begin with. 
anyway, my wife figured that i should model peeing to him so he could at least get the picture of what we're trying to teach. 
he thought it was hilarious when i showed him how to pee. 
he loves everything water, especially splashing. so, he was thoroughly entertained at the sound of the pee hitting the toilet water, and he'd always lean over to see the pee hit the toilet. i made a mental note that some times he gets overly excited and i better watch out because i don't want to pee on him. 

well, one day it happened. there must've been a lint stuck at the end or something -- but all of us guys's have experienced this: when the pee stream splits. 
and sure enough of, one of the splits landed on his head. he started squealing in glee thinking this was a game. i was horrified and mortified so i yelled, "move!" (which -- according to the rules of fostering, i'm not supposed to yell at the kids) then i pushed him back (another no-no when it comes to the rules). he thought it was a game and tried to come back to toilet for whatever reason. in the mean time, i've stopped midstream and am freaking out trying to figure out what to do. i turn on the shower head and tell him to get in the shower (probably another no-no, since he's going into the shower by himself...?) and return to finish peeing after no longer being able to bear the burning sensation. 
he's just watching me finish peeing while playing with his wet hair. 

i felt awful and horrible. well, i still feel awful and while i hope he remembers lots of stuff from our time together, i hope this memory is long gone from his mind.
