I thought I was hot stuff, last night, while I was sewing in that zipper.
Do you see what's wrong? Maybe not.
The zipper pull is on the inside. So, I've torn it all out and started again. The moral of the story: do not attempt something new while drunk and watching an extremely compelling video.
This little episode reminds me of one my favourite quotes:
If you can't be a good example, then you'll just have to serve as a horrible warning.
This motto has served me well.
