i have nothing against people who play SL the way they want... but i have to agree with this post.
i don't personally care for kids, and i certainly don't want to deal with them in a vitrual world... but again we certainly don't have a choice in who we ineract with when we go out of our home spots.
the last thing i want is for some "kid" to be asking me or their "parent" why i have something extra (prim bulge) under my skirt. (first of all WHY are you looking under my skirt in the first plac?!). then saying i flashed them and tried to get them to look when i was just window shopping for freaking hair. (yes i was in a mature sim.)
i know my Mistress and Master don't wish to deal with them, because my Miss actually had a kid avatar click her tail (and the tail script clearly stated naughty, nice, etc) and the little "kid' clicked the naughtiest menu option. and she usually didn't have a problem with the tail until then.
that's just some examples why i don't like dealing with children.
EDIT: yes i know not all people who play secondlife as kids are like that.... but i unforunately (along with several other people i know) have met the perverted child here in secondlife most of the time.
