myshadow, I agre with you, you can talk all you want but u will not get girls to give up their cell phones.
Just a story to show how sad pp are, so connected to their phones:
Rabbi Wallerstein was giving a shuir, and in the middle someone came in whispered something into his air, he told the crowd he needs people to pass up tehilims and siddurim which they will get back later, he got a whole box full and took it out of the room. Then later on in the shuir he told the crowd that he needs people to pass up their cells phones and after the shuir they will get it back…he got two cell phones!!!! Girls are willing to give up their tehilim siddur, which their grandparents in the holocaust would pay anything for, but their cell phones??!?!? a peice of metal?!? the story was vey scary and awakening to what cell phones have come to. not only can you do bad things with them, they become obsessed, I learn to limit myself so it does not come to that, I turn my phone off an hour before shabbos and on an hour or more after, it just makes sure that I am in control rather than friends who sleep with the phone in their hands.
