Forget the death and taxes thing. It's trite. Go instead with these three:
1) when riding bike, no matter which way you turn, the wind will be in your face. I can't explain it. I can only complain it. Just when I expect the whee of wind at my back, wham, wind in my face. Or could it just be I? Perhaps I expect too much? Hmmmmm.
2) there is no way to weed a rose garden without drawing blood. No matter how careful I am, someone plants a rose twig somewhere with the thorns pointing at my hands. Or I lose concentration and reach through the bush to pull a weed. Or I'm just plain stupid. Whatever the reason, there is blood. (Side note--the exception to this rule could occur while wearing gloves. Gloves? While weeding? Wuss!)
3) It's geometrically more fun to make a mess than clean it up! Bread is proofing in the oven. Kitchen is a god-awful mess. Think I'll go mow the yard.
I lied. There is one more thing. You are loved!
