I'm sorry, I can't think of anything I hate to do. I dislike putting down the things I love to do for things I am not as fond of. Hate never enters into it though.
Instead, how about this: I will hate it when my beautiful Valentine flowers are completely wilted & I have to compost them. They smell like Heaven, and I have such good husband-feelings every time I see/ think about/ smell them. *happysigh*
