I have a cordless electric carpet sweeper, which is great for a quick tidy up. However after around 4 years, the battery went into a huff and refused to charge up.
I ordered a new battery which is due to arrive today, so I plugged the sweeper in to charge so it would be ready to go once my DH had put the new battery in.
Some thirty minutes later, I realised that actually I was charging the dud battery, not the actual sweeper! 😳
Obviously stupid.
Please tell me your obviously stupid moments to make me feel, well, less obviously stupid.
