Exactly my take. There can be a privacy and trust issue with tracking and location sharing, but the way my wife and I use it, it's a very casual thing so I can see if she's on her way home yet or something like that without having to have her text me while she drives.

I have nearly the exact same situation. I like being able to see when my mom is visiting my sister or some other place we used to go, and I like my mom being able to see what I'm up to, like when I visit museums or parks. Sometimes on a phone call she'll say "I saw you visited ...some place... so I looked it up online. Did you know ...something interesting about it...?"
