Color makes a HUGE difference.
Also with cars.
Mrs RUFUS wanted a black car until I had her lay her arm on the roof of one and told her to keep it there as long as she could.
Almost instantly, she pulled it off.
Then I had her put it on a white roof, and she said it was hot, but she was able to leave it there for as long as she wanted...
Mrs RUFUS has a WHITE car now...LOL
