My wife still laughs because on the odd ocassions I cook (her choice) I use a mixer blade in the cordless drill.
Works for me....
When I cook, I am usually left alone, having been through this many years before. My wife used come along and turn things up or down and generally get in the way.
On one occaision it got out of hand and I took the hump and wandered off leaving the kitchen, with the passing comment "if you want to intefer cook it your damn self "etc, off I went into the shed. She took the hump and did the same and we both let it burn, no food that night and a bloody great silence.
Still its an ill wind as they say, it did clear the air and we really have not had many issues about since and its about 25 years on. We both cook and have learnt to be very diplomatic in our suggestions.
