two of my freinds just came to my door telling me not asking that im dressing up as a hooker for halloween help.....

well first thing don't tell them it's childish or u don't wanna look like a slut because that will definetely hurt there feeling's trick or treating is for all ages so go for it but maybe say you already dressed up as a hooker or heard that some other girls were dressing up as them ask to be somebody else or just fake being ill at ther last minuto that's just my opinion

It's not childish to dress up for Halloween as long as it's slutty... You should go as a hooker and be one for one day.

Well, dressing up as a hooker isn't exactly what you call childish, no?
Unless that's what children are doing these days....

Just tell them no. That you don't want to dress up, and even if you did, you wouldn't want to be a hooker. You decide on what you do or do not want to wear for Halloween.
