Giving your back to someone in a group.
(San Antonio, TX)
In a group gathering with several friends, some are across the table the others are to my right. I am at the end & the one to my right is totally giving me her back, excluding me from conversation. I feel totally out of place & finally ask her if she wouldn't mind not to give me her back so I could join-in the conversation. She turns back to the other girl, rolling her eyes to the other girl who also opens her eyes wider. I simply tell both well if you don't want me to hear then sorry for asking & the other girl says oh no. I say well you both are rolling your eyes so I figure you don't want me to join-in. Nonetheless, I felt totally out of place.
Isn't this poor etiquette to give your back to someone you consider your friend?
