AL TASHLICHINI!
Rivka, a woman of over 80, asked her son:
That evening Moshe took his mother to the kitchen and showed her the plates, cups, biscuits and cake, and he showed her a paper he had stuck on the fridge:
1) Serve tea
2) Serve biscuits
3) Offer tea again
4) Serve the cake
That evening the ladies are all seated in the salon, and Rivka, the hostess, went to the kitchen.
She reads the note on the fridge: 1) Serve tea.
With a smile she takes the teapot to the salon and served the ladies their cup of tea.
After they have shmoozed for some time, Rivka goes back to the kitchen and reads the note on the fridge: 1) Serve tea.
With the flair of a gracious hostess Rivka takes the teapot to the salon and served the ladies their cup of tea.
This repeats itself another two times.
Eventually the ladies leave.
Later that evening Moshe comes home and to his surprise sees the plates, biscuits and cake still untouched in the kitchen.
