Oops, again!

According to SheWhoMustBeObeyed, I'm developing a worrying propensity to forget what I'm going and go off and do other things, to the gross detriment of the initial task.
This is an example of the results of such forgetfulness, apparently.
I started to cook this demi aubergine, in chilli oil, at around 10:10 this morning.   SWMBO returned from cyrogymtwisty thingy at around 10:20 and, as pre-planned, drove me to my golf appointment.  Her next task involved trawling the local s'market for bargains / extravagances.  She returned home at 12:15 (what takes so long???) to find our home full of acrid smoke, and this group of carbon lozenges resting in the remains of a recently purchased, non-stick, frying pan.   I can tell you now that the pan may well have been non-stick earlier this AM, but it ain't now!
Note to self:-   Remember to check the hob before leaving home, or stop cooking when alone in the house.   :-)
