My parents had to instruct us to stay away from what my little sister called ‘dog armies’ that roamed our suburban neighborhood. Plus, a pair of neighborhood dogs cornered and killed my mom’s old cat.
It’s no problem if you have a Chemex and a means to heat water. We have a Coleman stove, but we also have a gas water heater. We can turn the temperature up on the water heater and have hot-enough water flowing from the kitchen tap to make coffee, or tea—maybe even poach an egg. (Our problem would be remembering to turn the temperature back down.)
Depends on how long you shower. We have a toe-step plug in the tub. When I shower, I like to push in the plug so I can, at least, soak my feet. A far greater problem for me is stepping into and out of the tub. But, it’s a caste-iron monstrousity (took a crane to put it into the bathroom before the outer walls of our addition were completed.) The tub won’t be leaving in my lifetime. On the other hand, it keeps me on my toes.
