I can't leave the house without a shower even if it's just a quick 5 minute trip to the gas station. The only exception I'm willing to make for this is if someone else is in some sort of harms way from nature or whatever.

Wake up late to the thing? I just won't be doing the thing I guess or everyone will have to wait. That said, I'm good about not being in that situation and plan myself well for the sake of others as I recognize it's a weird thing about me, not them.
