I'm sorry, but this teen we have working as a summer youth temp in my department is annoying 😑

We have four teens working in our department in my company's wonderful summer youth employment program. The other three are okay, but the youngest who's 13 just gets on my nerves. He's friendly and all, but he talks way too much and just never shuts up! And on his first day of work this week on Monday, he called me "bro" and today, he just called me "dude". 😡
