I get to Tonka's classroom the other day and one of the mother's says to me.
"You should know that peer pressure works.
Jane saw that Calanit had her nails polished. Jane wanted her nails polished as well, so she stopped sucking her thumb.
Then, Joanna, who started sucking her thumb only because of Jane, said she wanted her nails polished as well, so she stopped sucking her thumb."
I called my sister, Kira, who was the first person to paint Tonka's nails and told her about the revolution she had caused in the nursery school.
Peer pressure can be good, eh?
Note: names changed :-)
