A family affair

A week ago or so ago, I had to take our bathroom door off as there was something sticking under it and it wouldn’t close properly.
We live in an old house and the door is very heavy.
We, as a family, have made various attempts to re-hang it without much success.
This has involved electric screwdrivers, chisels, wedges and a bit of swearing from me.
However, success today, with a bit of lateral thinking (not from me)
