One rule for social media is that you should watch what you say, or if you're not going to watch what you say, at least block your mom from your feed. Mom is either going to cut in with some comment to knock you down, or you're going to feel total shame when she likes your post talking about all the tequila shots you downed at the back of a grocery store parking lot.
In this situation, mom was quick to jump in when this young woman posted a backhanded complaint about her upbringing. "I didn't know how poor I was growing up" is not a becoming statementof a nyone, especially if you had a swing set. It's not that a swing set is expensive, but the hospital bills are when you fall and break your arm. The girl tries to defend her comment, but mom isn't having it, threatening her with the block. That might actually be for the best.
