Class reunions are always a nice opportunity to catch up with old friends and have a pleasant evening... too bad that for your girlfriend (whom you met in high school), Luna, this turned into the only opportunity to outshine her historical rival!

“look how fat she's gotten”, she comments looking at her cell phone smugly, ”it's really a shame how some people let themselves go with the years... luckily I look exactly the same as I did in high school!”
She smugly puts on her old cheerleading uniform, which is now really tight on her, totally unaware of her current body shape.
You try to reason with her but she begins to be cruel to you as well. Nothing will change her mind: tomorrow she will show up like this at the class reunion, and she will delight everyone present (and especially her rival!!) with a marvelous choreography!

All you can do is indulge your fat girlfriend in denial, admiring her wobbly belly as she improvises clumsy choreography steps. It's going to be a long day tomorrow...
