The funny thing is that when the irrate bicyclist explained to you that she cannot ride in the bike lane because people stand in the bike lane, or throw garbage there, she could have screamed and threatened THEM with throwing her bike lock at THEM.
But it all came out at your BECAUSE you challenenged her by intelligently confronting her with the question.People do not like that. They become animal very quickly.
Only when I first became frum did I find there was finally a nation of people (us yidden) who could ask and answer safely in a non threatening atmosphere.
