Offend - never.
I remember when our youngest was born, a Tuesday tea time, I was in such a hurry to get to the pub as we had a darts match that evening I forgot to phone, from the hospital, the in laws to let them know they had another grandchild. Only remembered when i was half way to the pub so I had to stop the car, find a phone box and ring them.
By the time I got to the pub the match had started - and I had been replaced.
