I get that and normally, I don't mind conversation. I mind people being rude or obnoxious. I'm actually rather talkative with strangers and often talk to people on the bus (mostly when they strike up the conversation, though) or with cab-drivers. I am friendly and I get what you mean. It's considered weird to talk nowadays , mainly because of this "marvelous" technology.
Personally, I think there's friendly and creepy and a fine line in-between. :D
Frankly, I don't much like that question :) I don't really like explaining my tattoos to anyone...It's not a personal thing or anything, hope you understand. It's to do with someone who means a lot to me and is over three years old now. The tattoo, not the person. :)
Excellent answer. Peace.
