I really don't know how to be anyone else, and whenever I try to be anyone else, I fail miserably. Or I disappoint myself. It doesn't build my self-esteem, and it doesn't help me grow me at all.
I still owe a duty of loyalty to my clients and former clients, so I cannot specify which clients I did not especially find congenial, but the cause was the same.
I'm never comfortable at theatre opening nights. If it's my own production I'm too wound up to be able to enjoy the performance and too wary to enjoy the event as a social occasion.
