Erin and the kids are making plans to visit our friends' farm. Jane remembers a run-in she had last time with a donkey named Ruth.
Jane: Ruth pushed me over. Twice.
Erin: I think it was just once...
Jane: Why would she do that?
Erin: She was jealous.
Jane: Why would that make her push someone over?
Erin: If I spend extra time with Henry or Alice, you feel jealous and it makes you impatient and sometimes even angry.
Jane: You sometimes get jealous, too, Mum.
Erin: Not really. Older people usually learn to be patient about things like that.
A light clicks on in Jane's mind: a realization of a universal truth.
Jane: Donkeys and children get more jealous than mummies.
