What has changed recently is the open disapproval that sets in at this point. Mom and I continue chatting but Lyn has finished an has decided that we need to be finished too. She has started glaring at Mom and after a while will say again that I need to go because I'm tired. If Mom tries to distract her, she increases the use of The Look. It really has reached a point where it is non-stop. If Mom and I talk for another 45 minutes, Lyn glares and mutters for 45 minutes at least.
A couple of times, Mom commented that "if looks could kill, I'd be dead." That upset Lyn even more. So, now Mom asks if I want a daisy. When she mentions daisies, I know she's telling me that my sister is being her lovely and charming self.
Lyn hasn't figured out that referring to a daisy is calling out her glares. She's not upset when she hears Mom say this. So, it works out. She can continue giving The Look and Mom and I can chuckle about it without hurting her feelings.
