I don't get why people even post these things about their family online. Why? What does it do for you to, like we used to say "show off" like that? I never posted anything about my kids online and we just live our lives for ourselves. It is a strange new way of "keeping up with the Joneses". I am also with you on not caring what anyone thinks about my parenting. My husband and I have an amazing relationship and are happy, our kids are grown now and are happy. We all love to spend time together, etc. What do I care what anyone else thinks or says, I know my life is great.
I don't know why other people post things online, but I can share why I do, and it has nothing to do with showing off or keeping up with anyone. You asked, "what does it do for you?" This is what it does for me! I view Facebook as MY personal diary. I don't make posts for other people; I make posts for myself and our family. I post pics of our vacations and travels, post pics from my town (like our town hall decorated with Christmas Trees) post pics of our family celebrations etc. I also "share" things to my wall, that I want to read later. For example, articles that I see on National Parks or Disney that I want to read later or share with my husband or kids. I've been known to post pics of Easter baskets (gasp) etc. For me, I am not showing off, because I could care less what anyone else thinks and maybe my baskets are small or unimpressive. But what I like to do, is the following year, I may look back on that old post to remind myself what i did the year before for Easter.
Not a week goes by that I am not looking back on one of my old posts as a reference or reminder to myself. Last month one of my husband's co-workers was planning to trip to Moab Utah and wondered where we ate and stayed when we went 6 years ago. We have had a ton of trips since then and neither of us remembered. But it took me all of a few seconds to bring up my posts of Moab and right there in my pics and commentary was where we stayed and ate.
Did my Facebook friends think that I was "bragging" when I posted pics of that trip? Perhaps! But I don't care. I don't post pics on MY Facebook for other people, I post for myself and our family. Before Facebook, to answer the co-workers question, I would have had to dig through photos albums, boxes of pics, old journals etc. to find answers and I most likely wouldn't have bothered. But, with Facebook, I found the answers quickly and then my husband and I spent probably a half hour that night reminiscing about that trip. All thanks to Facebook!
I also happen to have a very small "friend" list on Facebook and don't accept friend requests from most people, unless they are a close friend or family member. In addition to my small friend list, about a quarter of the people who are my friends are actually blocked from my posts, but they don't know that.
I LOVE Facebook. It wouldn't even cross my mind that someone posted a pic of a vacation or Easter basket or family celebration to impress little ole me!! Haha! This goes back to my previous post. People need to have self confidence in themselves and their decisions and choices. If you feel good about yourself, then seeing pics on Facebook of someone's Easter basket or vacation, isn't going to affect you. You'll either look at the pics because they interest you or you just keep scrolling.
For me it has nothing to do with keeping up with the Joneses. I have less than 100 Facebook friends and I have never thought that their posts are bragging.
Do some people love to brag? Of course, but it's not something that would jump into my mind because of someone Facebook post.
