waiting for the cupcakes to cool

so i made wacky cake cupcakes about 30 minutes ago....and i made the icing....actually my mom made the icing....and i happily tested it...since i have no idea how she makes it....but it always comes out amazing....so i was about to put the first dollops of icing on the cupcakes and i hear a bleep from my computer...it was an im....from my bestest friend karen...saying hey...so of course i say hey back...and we get to talking ask each other what we r up too....she says she's swamped in hmwk...and i say i'm going to put icing on the cupcakes i took out of the oven....and she reminded me of the time we made a chocolate cake...which tastes amazing by the way....and put green icing on it when it was still hot....cause i had to go home....curfew...what a fun thing....well....the icing didn't look so pretty and it got really watery....so instead of icing my cupcakes....i'm writing this...saying that i'm gonna wait till they completely cool...like u really should....duh!!
