history: I forgot my mother-in-laws birthday this year and can't look her in the eye! My husband was working away from home and forgot to remind me. I forgot my mother-in-law's birthday this year and can't look her in the eye!
current: I'm sure she understands, just tell the truth!
next: I just feel so embarrassed - she never forgets my birthday. And my husband was away and didn't remind me :(
