When my kids were wee, on holiday in Spain, a well intentioned English couple gave them an inflatable pool mattress thingy for them to play with.
Unfortunately it was a union flag design. The kids didn't give a damn, but I dislike that flag with a passion. After about half an hour of pretending they didn't belong to me, I caved in and handed it back to the couple.
I still feel conflicted about it 20 years later.
