It's more false modesty to be absolutely honest. I used to do all the cooking. Then circumstances changed, we bought a business meaning hubby worked at home all day and I continued with my proper job, so he took over. This continued even after we retired and moved away from the business. I suppose I just got out of the habit and lost confidence, and anyway, he enjoys it. I never did.
I have mentioned this before, but a couple of years ago I was doing toast when the toaster died. I decided to do it under the grill, which is incorporated in our large double oven. I had absolutely no idea how to switch the grill on, and none of the knob symbols were of any help. We'd had the oven at least 4 years! I was disgusted with myself.
