Today I was at a team building event at a bowling alley with my coworkers, some of whom are also very good friends. My Russian friend A stopped on the way to get some fruits for his daughters and was kind enough to share a couple of them with us. He introduced me to a South American fruit today. He sliced the feijoa for all of us to taste and was surprised at my first reaction with my wrinkled face from the sour taste. He was right - it certainly is an acquired taste and with a second slice I learned to appreciate this delicacy with its 'sour on the outside but sweet on the inside' disposition.
Thank you, Anatoly!
