I don't want to say this, but
You're about to say something that will make someone’s day worse, and you're either a total idiot or you're just being real.
I don't want to say this, but your math skills are like a kid who doesn't know what 2+2 is.
I don't want to say this, but your face looks like a raccoon that got hit by a truck.
I don't want to say this, but your laugh is like a rusty door creaking.
