Absolutely get the neighbor to water those plants, you want Mom to come home to see how pretty they look and think about the 2 of you doing that together. Worth every penny.

Good luck with the cath tomorrow I hope it goes well and that the wicked ride slows down for you both. Glad to hear that you are also seeing the radiation oncologist. That may be an alternative option to consider. Not everyone gets surgery.
We all have sides of ourselves that we pick and choose who we show to. It's self protection.
