Sparks is a very confident mare and isn't afraid to voice her opinions and call out people. Most the time it results in a debate or argument, but when Sparks tried to call out a mare taking too long at the ATM, she learned that there are people out you shouldn't call out, like Nightswift, who's primary argument tool is a pistol to the stomach. Don't worry, NS isn't going to kill Sparks, Sparks is going to come with NS to a quiet place to "discuss" some things...

Just a funny doodle I thought of in my head.
