Blocked by a complete stranger

This is not too serious, so I'm asking out of amusement.

We went to a really nice weekend getaway to a gorgeous resort. I posted pictures and tagged my husband (I only post vacation photos or family related; never vulgarity, digs, or anything negative. My page is really beautiful and positive).

Last night, my hubby said an acquaintance of his, also Facebook friend posted similar pictures in the same place, I was "Oh cool! That's such a beautiful town. " I went to look on my page but only saw one of his posts, not the ones he was tagged in by his wife, because she blocked me...?

I don't know these people, have never spoken or seen her a second in my life. Honestly, this is the first time she was brought up to my awareness.

I have access to a company Facebook and checked, and I'm most definitely blocked. In the regular post, I see her likes, tags, and comments. In mine, all of it is gone.

Again, this is mostly amusing because I know I've definitely never done something to this person. I just wonder what makes a total stranger so triggered by another stranger that they feel the need to block them.
