Oh, I love random thoughts! I get them all the time! But since I'm now in my 50's & in menopause...my thoughts are not only random, but kinda fleeting. They kind of remind me of hummingbirds or butterflies. They flit around for a moment or 2 but if I don't catch them...they're gone!
But I'm not as bad as H (that how I refer to my hubby, Howard in posts). He has been doing it for as long as I've been with him over 26 years. I find it hard to read him some times, cause we'll be driving somewhere or watching tv & he'll just babble something I'll give a half-cock to my head & say, "Come again?" or "Context."
For me, it could be something as simple as a simple trivia fact or a story that kinda goes along with the situation. I also will mention out loud something I need/want to do, pick up while out on errands or look up online. I think I do that to help my mind remember things...cause it can really slip at times.
My guess is: WE ARE THE NORMAL ONES!! EVERYONE ELSE IS CRAZY!!
