Ouch! That sounds painful! But you really shouldn't be too embarrased...it was ICE afterall!
I once tripped over a SPEED BUMP (genius that I am - yes it was painted BRIGHT YELLOW! LOL) going into a grocery store, fell on my face and sent my purse flying, dumping all contents (including tampons!
) all over the pavement in a 10 foot radius. Now THAT is embarrassing!
Hope your knee feels better soon!
