I had this too, my mom's BFF just briskly said "I don't buy it!!" when my 8 month old was crying once. It bugged me too. First, there was no reason to comment on it, she wasn't exactly in charge of my kid, I was on it. Second, the tears were not fake, I don't recall the reason for the tears but they weren't fake. (Of course, when DD got older, fake tears did and do occur
I basically just reminded myself that she had been the mother of a baby 20 YEARS ago, and it's easy to forget ages and stages. I doubt she brushed off her own baby's sincere cries. It was just a stupid thing to say.
OTOH, my 3 year old neighbor was in our yard the other day with his Alan Alda-lookalike grandfather. 3 year old was trying to climb a 20 foot ladder DH had up to gain access to the roof (he was on the roof at the time) and we pulled him off. He started to cry. Crocodile tears for sure, it wasn't a question. Bad acting
His grandfather said in his Alan Alda way, "I don't buy it, kiddo" (with a smile). Then turned to me and said "Am I too hardhearted??" Nawww, I totally agree.
Am I too old? Does anyone even know who Alan Alda is anymore? (lol)
