Yesterday is long ago
[We stayed up late playing games at a friend's house. Laura was leaving with Jason (who is 9), while Brianna (who is 12) and I stayed a little longer.]
Jason: Why does Brianna get to stay up late but I can't?
Laura: Because Brianna doesn't throw tantrums the next day. Besides it's already way past your bedtime.
Jason: But I haven't thrown a tantrum since, like, yesterday morning!
