Dear Queenie,
There’s this woman where I work who always interrupts a conversation if she’s not interested in what it’s about and starts talking about something else, usually something to do with herself or her family or her kids.
Queenie, you don’t have to tell me how rude this is, but how do you deal with it without being just as rude yourself?—Conversation Etty Ket
Dear Etty Ket,
This woman seems extremely self-involved. I see no reason to worry about being polite to rude people. Feel free to interrupt her in turn, to tell her “Hey, you just interrupted me” and continue with whatever you were talking about before she interrupted you, or just turn your back on her and walk away.
