It seems pretty clear the friend is in an abusive relationship, so it really isn’t that simple. The comment you’re replying to literally described how their friend felt unsafe taking any action, especially with her child living there, so I think that’s your answer.
At work I’ve been thrust into a support function for some random system (I’m in analytics) and one of the roles I work with is fairly entry level, so lots of younger folk. I have been floored by some of the basic-ass shit I’ve walked them through. (Like explaining that you can copy and paste the url into a browser if the link isn’t clickable for whatever reason. Also had to clarify what url meant–is this not a common term anymore?) I had just assumed that because they’re younger and grew up with the internet, they’d smoke the hell out of me. But I guess interfaces are so streamlined these days many got away with never having to learn basic troubleshooting the same way I did as a millennial.
