I have never heard Pisces called that!!!! We are the last of the Zodiac signs because we have lived through all the other signs and have a few traits of each sign, but we are the most empathetic and wise of all the signs, we have learnt life lessons and have lived hard, which is why many of us end up addicted to something and suffer depression as we carry too much of others weight with us. Yes I suppose, in a way, that does make us a dust bin!!!
