I mean you could have said, “I’m sorry I was busy. I understand that being without your husband for 6 days and 6 nights for the first time while being disabled was very rough on you. I definitely want to hang out with you and I’ll do whatever I can to make sure we make solid plans someday soon. I’ll get your phone number and text you the next time I’m free and we’ll have a girls day out or we can just chill at your place. I didn’t forget about you. Don’t worry. It's your birthday this Saturday right? How about we hang out this weekend. I can come pick you up and we'll go out for a cup of tea.” But you chose the ‘Bite your head off’ option.
