Tuesday before Thanksgiving, a chronically late-for-family dinner (and somewhat estranged) cousin emails me out of the blue with the request that she come to my home for Thanksgiving dessert (she would be at her mother's near by for dinner). She says she wants her daughter to get to know me. I would be hosting dinner that day for 9 people, so I told her I'd love that and, because of my guests and our dinner timing, I'd be serving dessert no later than 5. Five, 5:30, 6….no cousin, no phone call. I held off dessert for a half hour, but we finally gave in. At 6:30 my guests left, leftovers were packed and put away, we were cleaning up and the PJs were on. Then, after 7, came the phone call they were on their way. I told her it wasn't going to work out, guests and food were gone, and I was exhausted. Her reply ( she is 43) was "Whatever" via text. The next day, I learn from family at her Thanksgiving dinner that she was napping on the sofa & playing with her daughter from 4-5:30, the time we were waiting to see and/or hear from her. Is it wrong for me to express my disappointment - after all, she invited herself - and ask her why she didn't call to tell me she'd be running late? As encouraged as I was to open my home (and heart), I'm now pretty bent…. Thoughts?
