Carolyn,

I know Bulgarian well enough; English is my daily-life language and also the one I am trying to become better at, for about 20 years now. My opinion after watching the clip:

You are clearly the only person behaving normally and capable to handle (and lead) a conversation, being able to “commit to the moment”. The “hostess” is mediocre and unnecessarily enthusiastic, Tzvetana Maneva (referred to as “the old lady” in the subtitles) is un-adequate, and I have no idea why the lady next to you was there at all…

I hope the Bulgarians participating in your life are open-minded enough to realize what a resource you are and try to intelligently learn from you.
