The first time I met my mother-in-law she didn't even say hi to me, just stared me down. She kept pictures on the wall of my husband and his ex wife and their wedding invitation was hung on the fridge still (from 9 years ago). The only time she acknowledges her grandson is when people are around and then she really over exaggerates the kisses and hugs and how much she loves him (in a super sappy way)! And whenever her other daughter-in-law comes for a visit from out of town she is so nice to her and tells her she's her favorite. Tells her how beautiful she is and how perfect she is for her son.
