Slob colleague.
The house you are engaged in rebuilding has taken over a year. During that time, your long suffering wife has been working part time and also looking after your less than 2 year old twins. We have had to suffer the stories and rants about the work in (or not in) progress.
Announcing that you have a move in date is very nice for you and your family and will be a relief for us.
To then announce that you are only taking the move in day off and counter suggestions that a day either side would be good with the argument that 'She will be home and can deal' is a cockish attitude.
You really do not deserve her and she certainly doesn't deserve you
