Honestly, with ADHD, that can be pretty normal. One day you forget to make your bed and suddenly boom, it's been 14 years since the last time you did it. Good habits die so easily because they give no pleasant hormones and bad habits come so easily because they give you reward hormones.
I honestly make my bed a couple of times a year. Also there's a theory that not making your bed is actually healthier because it doesn't create a warm, moist environment under the blanket for shit to grow in, so I use that as an excuse. But really, I just forget it all the time and don't care too much.
Yeah, the pint of the sub is you saw something that made you smile. Instead people were making themselves smile and posting about. Really they just wanted a pat on the back.
