When I don't want ice cream I always go to the local ice scream shop and tell everyone I don't want it.
That is funny! Well you would if you had a Mother Teresa wanna-bee complex and felt the overwhelming urge to be the savior of others and warn them not to eat the dastardly ice cream. ;)
"Don't eat it! It is bad, evil! I ate too much once and got a tummy ache! Don't be like me!"
