Some people dont always realize that when they are having a cell phone conversation, they tend to talk loud - kind of like people who are wearing headphones and start to sing are singing very loud.
The other day I was in line at WalMart and this yeshiva guy (BMG) was ahead of me on line. He was talking very loud throughout the whole transaction, and thanks to that I now know two interesting things about this complete stranger:
1- He doesnt want to start dating yet. He wants to learn one whole zman in yeshiva first and THEN start dating.
2- He prefers boxers, the kind with Superhero comics printed on them
See -you never know what juicy tidbits you'll find out about people, if only you are alert...
