"However, this person seems to be very immature 
and irritating (plus I just hate hate HATE e-
mail shorthand) so I think I wouldn't want to 
accommodate them just on general principle."

lol.  I know. I get these urges to write 
back, "I'm really sorry, but I am only completely 
fluent in English & I do not understand the 
language you are writing in. "

However, my lovely & intelligent cousin speaks 
this way in emails (including "Yo wassuppp???") 
so I decided to hold my tongue :)

As to not a problem, they will still get it.  I 
imagine they had a US friend bid for them.  Which 
I have no problem with.

Minion's chibi ninjas will be welcome as mine 
leave the bathroom a mess :D
