There is also the aftermath of the time away. The spouse has become so used to doing everything that the returning spouse feels unneeded. This can also cause problems and requires the right attitude.
Second that.

I have returned, and I am the man of the house, depend on me damnit...

After spending months away, and returning home, seeing how the wife was quite capable without me taking care of chores that I designate "mens work" - lawns etc, it would take a while for things to settle down again...

My best turn around period was 4 days, was away for 6 months south of NZ, then spent a further 9 nine months away, must of really pist off the postie for that one...
