Me and the big fella have come to a kind of rapprochement. It's a little one sided but I can live with it - for now.
He doesn't try to eat my head anymore and I keep him supplied with Polo mints. It's not so bad because I just liberate them from my daughter's "hidden" stash.
It's a pity we're not allowed to give chocolate to horses because he'd be in clover, and probably something else infinitely more smelly every morning.
