If you can't say anything nice, don't say anything at all

I remember in the 8th grade me and some friends were planning a slumber party. At the time I lived with my aunt and uncle. We were all trying to figure out whose house it was going to be at and they all said "their 'parents' wouldn't let them have that many people stay over", so I said "mine would". My friend quickly responded "Tabi you don't have parents." I will never forget how embarrassed/upset/hurt that made me feel. 

I guess what I am trying to get at here is that you should really think about the things you say before you say them. Because some things really do vividly stay in your minds forever. People these days always try to find others biggest weaknesses and use them against them, not knowing that it can really affect someone. 

So please think of what you say before you say it. If you can't say nothing nice, don't say anything at all.
