I hate to even say this (as I assume saying it will end it) but I think we might be turning a corner in terms of engaging back into the world of adult conversation. We went to dinner at some friends house this week. There were 6 adults and 4 kids. Samuel and Oliver played almost entirely on their own the whole night. Oliver played close to us much of the time (and sometimes under the table) but they each required very little parent intervention. It was amazing. On the drive home Kevin and I both commented on the fact we started and finished multiple conversations without interruptions. That just hasn't happened in, say, 4 years!
Maybe, just maybe, we've turned a corner.
