We took 15 year old DD to extended family's gathering this evening. She knew half the adults and DC there but DD is the eldest DC by 10 years so wouldn't want join in playing with the DC she knew.
The other DC were strangers to her, although similar age. We were only there an hour and she just sat in her chair, looking very bored. Replied politely when spoken to but didn't engage at all beyond that. The other teens knew how to listen to the adults conversation, chip in a little bit, generally looked engaged with the occasion.
I just came away feeling deflated that she looked like a sullen teen while the others seemed far more confident/able. I feel like I've let her down somewhere, haven't given her good social skills. I dont know, I just feel a bit shit about it.
