I drink my water out of quart mason jars and litter them in my wake.
I fill them and lose them only to find them on counters and desks, on stools and the floor near the couch or the window by the bed.
This trail of water means that I occasionally have to deal with a kicked over quart of water (a thing that is only helpful if you were hoping to mop the floor anyway, which I never am). But this also means I never have to go searching for a watering can (a thing that my plants would appreciate, but I never think to do).
So in the end my water jars keep me hydrated, spot clean the floor and water the plants. Not bad for a forgetful habit enacted by a messy woman.
