I really detest it when my wife decides to muck around in the kitchen while I'm cooking.
There is a lot of movement involved. Getting something out of a drawer, out of the fridge, out of a cupboard, etc. In fact, when one person does everything, there is a
lot of movement involved, except maybe during mise en place, when I spend a longish time at the cutting board. But, even then, I need to periodically get to the sink right near my prep area, or to the garbage bin underneath the sink. And, blam, there is my darling wife deciding to tidy up this or that and blocking access. Sigh…
So, my tolerance threshold is quite low. Quite often, I ask whether she can do what she's doing later, or if she please could leave me to it. Sometimes, I just walk out of the kitchen if nothing time-critical is going on and wait until she is done with whatever she is doing.
Note that the same thing does not happen at all when I cook with someone else, that is, when we have planned to cook a meal together and share the work. In that case, it's all about communication. "Could you do this while I do that?" and similar. And when, from the start, I know that someone else will be in the same space with me, my tolerance threshold for the occasional log jam is really high. Even though I inevitably "collide" with the other person every now and then, I don't get annoyed because my mindset from the beginning is different.
I guess I need to work on my mindset when I'm cooking alone, or on my tolerance threshold…
