Myshadow. You wrote. “I’m very pro kosher phones because I think it’s very important for kids to be able to contact someone in case of an emergency”.
Thats great. We are discussing boys in Mesivta. If chas veshalom there is an emergency, the yeshiva has a phone, and will surely usde it to contact you. If chas veshalom there is an emergency and you must contact your son, the same telephone will get you in touch with your son. Are you that concerned about your son o the trip to and from Yeshiva? Dont let him walk or ride the bus alone. Make him go with friends. Provide transportation. Why does he need a phone?
Again, can someone please explain why a mesivta bachur needs a phone at all?
