Update.

After our short trip over the weekend, I came back with enthusiasm to carry on with my pond. 
Have you ever had one of those days when you wish you hadn’t started

I had trouble with my electric saw, 
I drilled things in the wrong place, 
I put some wood in the wrong way round and had to take it back out
I hurt my back and dodgy hips climbing into narrow spaces.
I thought it was going to rain so cleared away power tools, it didn’t rain. 
I GAVE UP.
