LOL rightly so, and when you live in an apartment, it gets even more interesting. I have serious space issues when it comes to this stuff, but I adapt.. I was raised on the road (carnival), I know how to pack tightly confined spaces with maximum potential. Unfortunately, rain barrels and such, well, I'll have to use other things..
you want hot water? Here's a carnie tip: Get some black industrial water hose, about 100+ (the more hose, the more water) Fill it up (put a nozzle on it), and let it sit in the sun a few hours.. it almost boils. you can do many things with minimal effort, just use that imagination god gave you.
