Halacha from the Heart

I have a gift business in which I sell glass candy bowls filled with candies, fruits, and nuts. Must I toivel these dishes before I fill them?

I learned that one should prioritize giving tzedaka to relatives over others. I give a nice amount of tzedaka, almost exclusively out of the family (which also has a few poor people), which I feel is more altruistic. Can you explain this halacha and give some halachic guidelines?

My wife shopped at a special kedushat shvi’it fruit distribution. A few hours later, I spotted on the walkway to our building (of seven apartments) a single fruit. I took it home and asked my wife, who said it made sense that it fell from her, but asked how we can know it is not from a neighbor who might have also bought. Do I have to put up a sign or ask neighbors (whom I trust) if it could be theirs? Is it more lenient because there is no ownership of kedushat shvi’it fruit?

There is a special bassinet that provides motion and soothing noise and reacts to an infant’s crying by intensifying them. Is it permitted to use this bassinet on Shabbat, and if so, are there special instructions?

A congregant of mine is trying to sell his house. His non-Jewish real estate agent suggested doing an open house on Shabbat, a good time for many buyers. If the owner goes away for Shabbat, may he do that?

After I fastened the tefillin shel yad, I realized that the beracha I had recited was not the one for tefillin but that I had instinctively said Yotzer Ohr. I continued davening with just the shel yad until the next semi-break, Yotzer Hame’orot, at which point I put on the shel rosh. Was that correct?

I do not understand why some people keep chalav Yisrael today. Do they really think that someone is adding pig's milk? My friend quoted his rav that it is more important to keep chalav Yisrael today than it ever was before. How could this be?
