Can one give a present on shabbas? If the answer is no, then how does it work when one eats by someones house the food one gets is a present (it is changing reshus). Sources please.
My family is not frum, and my grandfather gives out money to all the grandchildren at our seder. I refused the money, but my father took it and put it in my room. Can I use this money?
When people go away for shabbos they often bring along a gift to their hosts. What is a good Kosher wine - not too dry - that you can give for less than $20?
