It's like getting your school report. You tell whoever wants to know, what your grades are. That is, if those grades are good enough to share. If they are not that good to show off, you won't mention them, would you? It's not like you would step up to people and say: hey, wanna know about the bad score I got on my mathematics test? You keep the scores to yourself and you hope nobody will ask about them.
You can tell people about your bad day at work. How crappy it was and how you hope it will end soon. Will you also tell them, that bad day was caused because you went to bed late after an argue with your husband? Is it to their concern that you didn't sleep all night and you want your colleagues to take the blame for your bad day? No, FaceBook will only state: terrible day at work.. and your followers will get back to you saying how sorry they feel for you and that they hope you will have a better day tomorrow. Because we don't want to share what went wrong..
Trying to show the best of us, is what we were brought up with. It was important to our parents, to show how successful you were. It probably makes parents feel better about themselves, if their children do well in school, at work, in their social life. They'd rather not have others know that their son drinks because he can't cope with the high standard life has brought him. They don't want people to find out their youngest got kicked out of school for the second time, so they say he switched school because it had more opportunities. Because we all want to look our best. It is important to us that people have a good impression about who we are.
I'm always happy to share good blood work when it comes to diabetes. I like my numbers to behave and I have no problem typing them down for others to see. Every now and then I even share images of good graphs and "perfect" situations. Because it takes hard work to get those numbers and you put a lot of effort in it. Doctors ask you to do your best and make sure that HbA1c is below 7%. Because you don't want to get nasty complications, do you? They state the importance of having your numbers within range (and the margins become tighter over the years). Not one doctor prepares you for numbers that are way out of line. They don't tell you it is more likely to have off numbers than readings that make you feel good. So you want to live up to their standard. You want your D to be in control. Because you want to look your best. Diabetes isn't easy. It's not always the way you want it to be. It is hard to admit. It doesn't make you a terrible person if you let others know your numbers were way out of range. Then why is it so hard? Why don't we let others see our dark side? I dare you all, to post your worst self pic ever. I challenge you to write on your FB status: "Did lousy at work today. I made my colleagues look bad and I screwed up on a very important job." Don't be afraid about the comments you'll get. I won't fear the comments after having posted a crappy D-day, due to miscalculating carbs for that wonderful cheesecake, high readings, pump sites that stayed in way too long.
I dare you.
