The other day I was strimming our hedge. Doing the sides was easy enough but it was a struggle reaching the top. Basically I was too short and couldn't reach those tricky bits across the top. Then I had a brainwave: attach a few helium-filled balloons to my belt to lift me up so I could hover over the areas I couldn't reach. Simples! Three balloons were enough and before long the hedge was done. Result The only problem was the strengthening wind and a couple of times I ended up in my neighbour's garden.
