person A: I forgot my mother-in-law's birthday this year and can't look her in the eye!
person B: I'm sure she understands_comma_ just tell the truth!
person A: I just feel so embarrassed - she never forgets my birthday. And my husband was away and didn't remind me :( 
person B: Yeah_comma_ I'd be pretty scared too_comma_ but it's better to be upfront about it to get it off your chest
person A: You're right. She's a very forgiving person and I've never forgotten before. It's on St. Paddy's day for heavens sake - how could I forget???
