Daughterly blonde moment

Some things simply have to be documented …. like Caitriona’s blonde moment of yesterday, passed on to me in her own words:

Classmate: What battle was in 1066?
Caitriona: Wasn’t it Hastings?
Classmate: That’s it! Blimey, well remembered!
Caitriona: Yeah, I even impressed myself. I don’t even DO chemistry!
