What makes you happy ?

Living next door to a child-minder, we get to meet lots of small people as our two introduce them. Today, there was a little girl of about 5 who P. was playing with, and she was shown and played with our ferrets. A little while later, the girl’s mum came to collect her. We heard this:
“Mummy, come and look at the pets”
“What pets ?”
“The flat rabbits”
