Funny Arguments

Hate having an argument you wish you never started? Just want to tell them your sorry so you won't fight? My older sister and I argue a lot, but we always hate it and wish we never did. So now, after watching a show that does this, we were inspired that whenever we start up a fight we will whisper loudly(so we are acting like we don't want people to hear, but of course they do) and talk fast going back in forth arguing. This will seem so ridiculous we burst out laughing. And when ever we're mad at each other one says,"suck it" and the other answers back,"you suck it" then you both say suck it at the same time and just laugh or smile.  If that doesn't work a truthful apology is best.
