Two men, moderately proficient in Yiddish, were lamenting the fact that there are Yiddish expressions that you can't translate well into English. Furthermore, there were some English words that cannot not be easily translated into Yiddish. One man said to the other, I have difficulty finding a Yiddish word that adequately conveys the concept of of the English word "disappointed." His friend said, "My mother speaks only Yiddish. I'll find out from her how to say disappointed in Yiddish."
The man goes to his mother's house and say's "Mama, you know that I always come over for Shabbos dinner every Friday night. How would you feel if, one Friday, I called and said I wouldn't be coming over for Shabbos?" The mother replied, "Oy! Ich'll zein zayer disappointed!"
