i am not too happy that i did not drive my mother to the airport
oh, no, i am sorry to hear that. you had no idea that would be the last visit, but i can understand how you would feel that way. i have no doubt she understood why you did not though.
i had an emergency at work. i am a doctor and it was a life and death situation but now i regret because i could have assigned someone else and driven my mother because that was her life visit
