I've noticed a bit of an interesting trend in tattooing in my part of the world. It seems that with the ever-increasing popularity and wider acceptance of tattoos, some people are looking to get a tattoo for sake of getting a tattoo. This is a trend fraught with potential regrets and disappointment....don't get a tattoo unless you have really thought it through. It is almost like when I was first getting inked some 25 years ago and people would walk into a tattoo shop drunk and pick something off the wall, for the sake of getting at "tat". I would rather turn away a client who seemed unsure or not really committed than let them get something they might regret later.

I know what you mean by getting frustrated about people doing things without reasons. That is a major pet peev of mine. whether it be someone buying a brand of clothing simply because its expensive or getting ink just to fill the space between. Tattooing used to be reserved for the wild and exotic. It was a outward sign to the world that one held certain things sacred, whatever those things were. It doesn't mean that so much anymore. and i find that sad.
