@ Markos; it's the same with me.... I walk into the garage, just to fetch something, glance toward sleeping beauty there, and then realise I can just do that one small thing and have no-one notice it.....and an hour later That-All-Important-Family-Member is annoyed by the fact that A. I am in my sunday attire upside down under the car and B. I went Missing in Action and C. the "something" hasn't appeared back in the house to hang that painting, or screw on that lamp.....
