oh LOL LOL as soon as I started reading it, I laughed, because that is exactly how I am. before I had cats, I had so many plants, with a note by each group and just the right size glass to water them. some take more light, others more water etc. !!!
I hardly pay attention to what plants I have left now!
last year when I went to Phoenix for a few days, I had just 2 cats, and oh, you would have thought I was leaving for a month! I left the vet phone and address, and the after hours emergency vet name and address, phone. the number where I was with room number, cell phone number!! the directions were pretty easy, at that time there were no sick cats, and no problem with them getting along! but I had to set everything out, to make sure there was enough food and water, I left water bottles out and extra food bowls with lids, so the neighbor just had to uncover them if the last one was empty. and I had 3 places where food/water was, plus a 4th where just a fountain is at, and I left more water bottles there. I had 3 or 4 litter boxes thru the house, instead of the usual (at that time) 2 ! and of course I called her after being gone for a day, then again on the day I was coming home. LOL.this years reunion, was in Tucson so I didn't need a sitter. next year is something else, I don't know what I will do with them, am already worrying! and I have so much more to worry about now!

well at least your friend understands , if she has cats
