well labeling, again, is just a label. you can let it stick on you or take it off. you see, through labels, people do get stronger and know their faults, the hard way. it all depends on the person, if one knows how to evaluate well, labels would not be a problem. Change for the better, throw away the dirt/label if its not beneficial.
And for goldfish, you can always say it whatever way you want. goldfishy, goldies, goldfisheses, up to you. Maybe ask a teacher if you like~
Hippoes stays hippoes. The singular is hippo.
& you label people everyday without realizing it.
'Girl' and 'boy' are labels.
'Young' and 'old' are labels.
