Lol same deal with anything really, people get a significant other deal with them for a certain time and then on to the next, people get any species of fish, get used to it get bored of it and want something new, that's how it goes I guess. Not everyone knows how to settle for something. In this day and age that is rare imo, definitely with my generation, I have a girl I've only been with for 2.5 years, you older guys probably would look at it likes it short, people my age say we've been together foreverSame scenario has piranha I guess, most people get them, keep them several years and then get rid of them.
