Do you own a whistle?
No, although I did take a monstera one time that somebody had put out on the curb. It was gorgeous and I couldn't let it die. (We live close to two college towns and when the students leave in the spring, the townies do a lot of dumpster diving. The students put anything and everything out for trash and a lot of it in good stuff!)
Do you own anything that you bought from a public sale or an estate sale?
I have three leather recliners, all in the past month and a half. To replace the ones the cats destroyed.
No, but I have a number of sprinklers on the end of water hoses. (And multiple thermometers for plants.)
Do you own a blood pressure meter?
I have lots of them from back in the day, but nothing to play them on.
Do you have any mouse traps? (Not the furry, four-footed ones!)
