I used to visit my granny on a Saturday afternoon. I arrived one day and she was waiting for the engineer to come and fix her telly. He got there just shortly after me and asked her what was wrong with it.
She said, "I think it's the tyre"
He looked at her then looked at me and I just shrugged my shoulders.
He took the back off the telly and had a look then turned to my gran and said;
"Yer tubes gone, hen"
"Aye" she said "I knew it was something to do with a bike"
In fairness my granny was renowned for that kind of thing, I remember she was in our house one night as my dad and I were watching the football.
She was getting exasperated trying to remember the name of this woman she had met at the bingo, and describing her to my mum. It was really annoying her that my mum didn't have a clue, "Oh for goodness sake Ellen you must know her, you were at school with her daughter, she lived in Blackwoods Crescent, married the wee fella McDonald, think for God's sake" and my dad said "Is it that wee Mrs McDonald?"
My Granny let a scream out of her and said "Thats' it, brilliant Joe, Do you know her?" then slapped my mother on the arm and said "How come he knows her and you dont?" I was rolling about the floor in tears and my Gran just thought I was mental.
