Oh I may be smart, but I'm not that smart :)** I don't know why
   I respond to things when I do.* I get notifications from newest
   to oldest, so I usually respond to newer things first. But
   sometimes I skip around and see what older things I've missed.
   Perhaps there is a calculator working deep inside of my brain
   that I can't see, but as far as I know, I'm behaving randomly.*
   But of course, there could be a pattern that I am not aware of.
