I bought her a trampoline. My wife did not think it was appropriate for someone her mom's age; but hey ... why not? You are as young as you feel your age; or whatever the saying is.
She had a nice barbecue ready with sausages, burgers and steaks. By the way, as an aside, I once had elephant steak. Have you ever had elephant steak? You'll never forget!
So I set up the trampoline in the garden and the children quickly had a go at bouncing up and down. To her credit, so did mom-in-law. She got out of the swimming pool and decided to try out her new toy which I got her. She is such a short lady. So short that her legs don't reach the ground.
I had to pick her up and lift her onto the trampoline. Once there she started bouncing higher and higher and somersaulting as she did so. She got up so high that her swimming bikini bra got caught up in the branches of the nearby tree. She just hung there like an ornament on a Christmas tree. We did not know what to do. I was concerned in case the bra strap broke and she'd come tumbling down and break the trampoline.
It reminded of the occasion years ago when I learnt magic and had practised levitation. It was at this very house where she lives. I got her to lie down on her back on the dinner table and magically levitated her. She floated up slowly until she reached the ceiling. Unfortunately, once she reached there I could not get her down again. She remained up there in a lying down position with her nose touching the ceiling. In my panic I forgot the magic word to bring her down again and I was afraid she might suddenly drop with a bump and break the table.
This time it was no different. If she fell down from the tree she'd break the trampoline for sure. I did the only obvious thing and moved the trampoline away.
My wife got very angry at me shouting at me to get her down. I explained that bra straps these days are made of very strong material and are unlikely to break - polyester I believe! This did not appease my wife.
We got a long step ladder from the garage and I was volunteered against my will and better nature to get up there and get mom-in-law down. It was not a pleasant experience. Going up there and holding on to her legs whilst I tried to untangle her bra from the tree branch. What if I fell? There was no trampoline down there to soften my fall.
Anyway, I got the bra strap off the tree branch. She sat on my shoulders, and I slowly step by step got down to terra-firma.
