I am completely impractical. I think I had something missing in my brain. Honestly! I can't do jigsaws and if something has more than one part, I can't put it back together. I am left-handed and awkward and accident-prone.
I don't know why.
When I was a kid, my mum was very practical and ahead of her time. Did all sorts, including mending fences, fixing a broken septic tank, did all the DIY - you name it. My sister and brother were both very practical.
As a kid (the eldest too!) I wanted to join in. I tried, oh God how I tried! I wanted to help Mum wallpaper and paint. Just couldn't get the hang of it and wrecked so many pieces, we couldn't afford for me to continue 
At school, I sat next to a boy in sewing class who was kind enough to put the thread on my sewing machine every time. I could not, no matter how I tried, learn how to do it correctly. One I jammed it so badly, the teacher thought I'd broken the machine. I was very upset.
We did metalwork and woodwork at school and also technical drawing. Hated those classes. Bewildered and confused from start to finish. Family used to have a great laugh trying to identify what the hell I was supposed to have made when I brought it home. I laughed too.
I was the bane of my metalwork teacher's life. He was always taking things off me like chisels and the welding flame thingy as he was so worried I'd hurt myself.
I was great at languages though, so it wasn't all bad.
I don't mind cleaning up pet crap and wee and sick. I did some auxiliary nursing which I enjoyed fine. However, I did have a problem using the hoists. Could never understand how to rig up the stuff and terrified I'd make a mistake and hurt someone. Always, always, got someone to check over my work before I used them.
Anyway, I am hopeless. I looked at a DIY book for women in a shop recently. Supposed to be for complete novices. I couldn't get past the first paragraph as they'd already lost me.
My husband is fantastically practical. He has saved us so much money over the years on tradesmen. Without him, I am going to have to spend a lot on professional help or go without, I suppose. Or try DIY and end up demolishing the house as a result.
