Very sad not to invite seminary girls.
For the kollel man who doesn’t know “what to do with them”, here is some advice:
1. You don’t have to do anything with them.
2. When they arrive, say hello. Ask them if they would like something to eat or drink. Give them something to eat or drink.
3. At the shabbos table ask them how they like their seminary and what they are learning.
4. Whatever they answer, say “that’s wonderful, I hope you gain alot this year”.
5. Sing zmiros
6. Say a dvar torah
7. bentch and clean up the table.
8. Let your wife shmooze with them while you clean up.
9. Go learn.
10. Repeat tomorrow.
N.B. If they want to clean up instead of you, go straight to your learning.
Now, was thast so difficult?
