That’s Not Quite the Same
When you end a relationship with someone, it may not only be the end of your direct connection with them. You might also have relationships with people that you met through your ex and therefore don’t see as often anymore.
If your ex keeps in contact with some of those relationships- like your parents- you might have questions. So, we can see why this person was confused, even though it’s laughable that they thought it was comparable to this person talking to their own father.
