My partner's parent has been single for many years. They have now become attached to another and it's great for everybody. But, they have this horrible horrible habit of expressing how people from their past "were so good looking". It's not an important footnote to say that you met this person or used to hang out with that person and they were attractive. If they are trying to make the new significant other jealous or insecure- please consider how it would make you feel if the role was reversed. Plus, you're 75 years old.
