Whatever your hobbies, interests or, God forbid, obsessions (Italy, Assisi, old books!) ... you can find something to buy on eBay. I realize this is not news but you kind of forget until you venture in again. It's like a pitcher of margaritas. It may sound like a good idea at the time but later on, "oh, yeah ... this is why I don't drink margaritas." Alas, sometimes you get a nice rush, a buzz and you find yourself thinking ... "must have ..." I mean, doesn't tequila do that? It's a bit dangerous.
