People who change the subject when you are having a conversation

[Helptonight]

Just that really. My husband has a habit that when I am chatting about something he'll just interject with some random thing.

Example:

Me: This crazy thing happened at work today, Susan decided to break in to song during a work meeting - it was nuts we were all so shocked!

Husband: Really?

Me: Yeah we all couldn't believe it!

Husband: I think there's something wrong with my car, I've booked it in to the garage.

????

This is an example but it happens constantly, talking and then random change of subject.

His old boss said the same about him once in a performance review. I said his boss was correct, he said sorry I didn't realise I do it.

Maybe he's not interested in my work story (entirely possible 😂) but it happens all the time. If I correct it he says sorry but it's so infuriating especially if it is actually important chat (about our kids etc...)

Anyone else experience this?

Mine is a lot like this too. It's mortifying.
He also makes really obvious jokes but in a loud and obnoxious way so it's impossible to move on with the conversation. Like if someone says something similar to a line in a song he'll start belting out the lyrics so the person loses their hold on the story and can't segue back in.

It's because they've got no interest in what you're talking about
