For me, it's the appearance that I don't care...about whatever it is people don't think I care about. Or not hearing when people talk to me...because I am so wrapped up in my own thoughts that I can't focus on their words.

Forgetting important stuff because I am rushing along on a personal jag of some sort or another.

Buying something and being totally into it, telling people I am totally gonna do XYZ, and then a week later being like, nah!
