Callistemon As a retired schoolteacher I'm sure your arithmetic is impeccable and to be exact we've been here exactly 49 y 113 days as we pass through yet another Solstice! and another Father's Day! with poor Dads and Grandads in lockdown!

So much progress has been made in those 250 years, especially in the last 50.
Good Health
