¡Ay, caramba!

I heard Wilson in the garden this morning shouting '¡Ay, caramba!'

I went out to see what was the matter and found he and Antony arguing because Antony said his helmet was hurting his head and he wanted to take it off.

Wilson had also decided that his helmet was uncomfy (and also kept falling off his head) so had decided not to wear it, while still insisting that Antony must wear his.

Antony said that this was unfair, while W insisted it so was fair because he was in charge.
