Your piece really made me laugh. I'm from English-Irish background and we as a group are notorious interrupters. Aaaand, I lived in NYC for 35 years. So personus interruptus, tis I.

For many of the reasons cited, I get excited by the conversation and jump in, like, yeah, I know, what happened to me....

But I've offended people, so I really keep a lid on the lips these days. I learn more about other people, but it is less fun in a way.
