I will not get involved whether its right or wrong in hashkafah for a bochur to drink a beer every so often or smoke a bit during bein hasdarim, bein hazmanim. But what I will give my opinion is to as why we as parents (b’ikar) also mechanchim rabbeim are getting stuck on bochurim drinking a bit, smoking a bit. Instead all our koichos should be almost entirely on the nisayon hador which not one bochur (also parents) are exempt from regarding shemiras einayim and the danger of smartphones. Its sad to see so many bochurim (even ones that look all innocent) who have fallen. Its about getting the bochur HIMSELF to understand why its the wrong thing, because w/o this theres nothing stopping the bochur from buying a smartphone from cvs(for $20) w/o parents knowing.( Agav, I do not work for guardyoureyes.com)
