Tell them clearly what you won’t tolerate. “Would you mind talking more quietly when you come into my office?” “I know you get frustrated by bad service—believe me, I feel the same way! But would you mind talking about it after work so everyone else can keep getting things done?” “It really bothers me to see you do these crazy stunts. Can you please stop inviting me?” Explain kindly and firmly why you need this boundaries in place. “I’m really sensitive to loud noises when I’m working and it’s hard for me to get focused again after I’m distracted.” “It’s just really distracting when you come in after lunch complaining about this kind of thing.” “I don’t like to think about you hurting yourself.” Set verbal limits for conversations and interactions. “Hey, what’s going on? I have to warn you, I have a call in about 5 minutes that I’ll have to run to.” “Sure, we can get lunch. I’ll have to go at about 1:30, though.” If they ignore your boundaries, tell them you’re not going to be around them anymore. “I’ve already asked you not to do that, and maybe it doesn’t seem like a big deal to you, but it is to me. I can’t be around you anymore if you won’t respect my boundaries.”
