Shut SMS #20

Rabbi Shlomo Aviner answers hundreds of text message questions a week. Some appear in the parashah sheets "Ma'ayanei Ha-Yeshu'ah" and "Olam Ha-Katan." Here's a sample:
Q: My son became secular when I educated him his entire life to be religious. Did I fail in his education?
A: No. There are other factors. All of your proper education is located within him.
Q: Is there a halachic obligation to hide pregnancy?
A: No. It is a personal decision.
Q: I am selling my car. Do I have to relate its problems?
A: Certainly, so you are not deceptive.
Q: Is trust in Hashem (Bitachon) the same as trusting that Hashem will send me the salvation which I expect to be for my best?
A: It is trusting that Hashem will decide what is for your best.
Q: Is it permissible to use one sink for milchig and fleishchig? How?
A: Yes, wash in the air or use separate racks or tubs.
Q: Is it permissible to lie to an insurance company in order to receive a larger payment?
A: Certainly not. This is lying and theft.
Q: Is it permissible to take an oath to Tzahal at the swearing-in ceremony? Perhaps I will be unable to uphold it, such as if I fall asleep on guard duty.
A: It is not referring to a detail such as this, but loyalty to Tzahal. It is therefore permissible to take an oath. But in general, we refrain from saying: "I swear" (since we refrain from oath-taking) and say instead: "I declare."
Q: Is there an obligation to take off my watch when putting on Tefillin?
A: You should remove it, but some authorities are lenient.
Q: If a woman is crying on the bus, should I offer her help?
A: Yes, a woman should offer help.
Q: Is animal experimentation permissible? Is there a limit?
A: What is needed for human beings.
Q: Is it permissible to burn disks from songs I download from the internet?
A: It is certainly forbidden. Copyright. The creator invested time and money!
