While at lunch my friend and I lost it. My seat was a little too far back well she went to fix it and then I was laying all the way back. We were laughing so hard we were in tears. Then we start talking about my niece and nephew and I said they are still needy cuz they need help wiping their butts. Well my friend said well I still wipe your butt. She meant to say she still wipes her daughter's butt who is 8 sometimes. Well then we lost it completely
