Oops! I ratted out my husband!

I feel really bad. I accidentally ratted out my husband to his mom!! He had told her that he had to do something today because he needed to get out of doing something that she was trying to get him to do. I didn't realize that it was today and she texted me and asked what we were up to today 😬. I told him to warn me and remind me when I'm supposed to be covering for him. Anyone else ever accidentally sell out their husbands?? Haha!
