Best thing: probably a bit more empathetic than the average person. idk if this is a product of stuttering, tbf. Worst thing: to pick one specific instance, I would say the time I had to give a class presentation in college and choked through the entire thing even after I was fully prepared with material and my argument. The stuttering alone caused me to go over time and it was the only thing I was deducted points for. An A to a C because I took an extra 6 minutes on a 10 minute presentation.
