Cruisin' for a bruisin'

Pride comes before a fall.
Hubris.
etc.

Example 1
Made my footballing comeback yesterday. 3 weeks after knackering my knee. I took it easy and it felt OK. And we won. And, at the end, my knee felt better than it had for 3 weeks.
But, oh, it was sore in the evening!

Example 2
Another highlight yesterday was making a comment just as Sobriquet was drinking a glass of water. She very nearly snorted water out of her nose.
Then, still chuckling to myself at her near miss, I sipped my cup of tea. And she made a comment and I did snort tea out of my nose. It was the National Trust tea-rooms all over again.
