a finger will always leave its mark

Blaaaafff..
You touched the cake that I am about to eat, again!

Eerrr..
It is so disgusting for heaven sake, to have a mark of your dirty finger

in things that I am about to enjoy
Why can you just mind your own cake, since you have one for your own?

Ah well, one is never enough for you, no?

uh, don't you think this cupcake is so cute?
