Going home for lunch to see your wife and your newborn baby is a great idea, and a lovely way to spend time with your family. However, please heed the following warning.
Carrying a baby when wearing a clean shirt is not advisable. Babies tend to throw up every now and then, and it might just be then.
In such a situation, you will be forced to change your shirt and go back to the office.
And guess what, no one even noticed I was wearing a different shirt !! I'm not sure how sad that is, but it must be high up there on the list !!
