the trash bag debate

as Daryl was taking out the trash a couple of minutes ago, i asked him to start thinking about not using trash bags anymore. when we run out of our current supply, i don't want to buy anymore.

here's our conversation:

Daryl: what do i use instead?
me: the can
D: how do i carry it outside
m: pick up the can, carry it to the big trash bin and dump it in
D: if i eat a trash bag can i keep using them?
m: WTF?!?!
D: it would show you that they mean a lot to me
m: why do they mean so much to you? (i ask like i'm unaware of his slight ocd cleanliness issues?)
D: they just DO
m: what if i were to wash the trash can out myself before it's brought back in?
D: ok. no trash bags

a few minutes later:

D: landfills are fine and there's all this research...blah blah blah (i stopped listening to him)
m: it's not about the landfills, it's about consuming less.
D: do YOU eat trash bags?
m: NO, less of a commercial consumer
D: oh, so you wanna save money
M: sure, yeah
D: ok. no bags....but we still have some left, right?
