Last night I went with my partner to visit his elderly mother in her rest home. We took along her toy poodle, Sammy, who we now look after. She was in such a crabby, negative, critical mood that by the time we left we both felt utterly drained to the core. I felt it starting to happen during the visit and did my "energy projection" thing, but she just vacuumed that up in a trice.
After we left I noticed that Sammy the dog was also hanging his head down. I said to my partner: "Look! She's even managed to suck all of the joy out of Sammy!".
To be fair, she isn't always like this and she has had a terrible year healthwise, culiminating in her moving to the rest home. But when she's in a bad mood, her energy-sucking powers rival that of Count Dracula himself!
I think she is an ISFJ, by the way.
