Great Uncle Fred was like an extra granddad to me (he took my dad and his sister in when their younger siblings made their house too crowded).
On dark winter afternoons when we visited him, he would give us tea and cakes. At some point during the visit, he would get a big torch from the window ledge and say, "I'm just going to check that the horse hasn't kicked his blanket off". He'd only be gone a few minutes, then come back and say, "he's fine".
As a child, I couldn't work out where he kept this horse among streets and streets of terraced houses. It took me years to realise that he was off to the outside toilet!!
Wotty.
