Question
I've heard that you should not drink water that was left uncovered overnight. I have a kettle that has a closed lid with water in it, but its spout is not covered. Does that count as uncovered water or not?

Question
I am right handed and am currently in the hospital for 3 days with an I.V. in the top of my left hand. I asked the nurse if it would be Ok to wrap the Retzuos over the I.V. site and she advised against it as she said it could stop the fluids from entering properly. Should I wrap the Tefillin shel yad on my right arm temporarily until I no longer have the I.V. or do I refrain from wrapping the shel yad? I am unsure of the halacha for this matter and have not put tefiilin yet today. I would greatly need a response before sunset.

Shalom, I have been reading the Mishneh Torah, the negative commandments. I am an artist, and learned to not make any human figure from clay. I am wondering if keeping dolls (since they too are human figure) is also something I need to get out of my house. Thank you so much for your time.

Question
Sometimes I travel by airplane with a carry-on only and no checked luggage. Included in my carry-on are my tefillin and siddur. Airport regulations prohibit leaving luggage unattended or with a stranger. What is one supposed to do if they have to use the restroom at the airport, but their tefillin and siddur are in their luggage that must be kept with them and therefore brought into the restroom?

Question
HI. I recently made a car rental reservation for an upcoming trip. I only have to pay when I pick up the car and can cancel the reservation before that. I then found a lower price with another company. Can I make a reservation with the 2nd company but still keep the first one, just in case there is an issue with the 2nd company when I get there?
