i have not bought anything on craigslist in real life. i think it is because i do not like awkwardness. what if i buy something from somebody, and then i see them months later at the shoe store? it would be all, “hey, how is it going? still using that coccyx cushion i sold to you for 5 dollars?” “ah, no, man, it burned up with everything else in the fire.” then we would say bye all awkward, but we would probably be parked next to each other and also live next door to each other. that would be uncomfortable for me on two or possibly three levels.
