It's good to know your mother well

There are quirks about me that I inherited from my mother. Most notably is the one relating to first thing in the morning. I'm just like my mother in that regard, except less unpleasant looking. Just give me several minutes to become coherent, and preferably wait till I've had at least half a cup of coffee before talking to me about anything. For instance, my father went with us to my in-laws for Christmas last year. After sleeping on a fold out sofa, I needed some stretching and strong coffee to wake up and deal with well over a dozen humans crammed into a double wide trailer in South Carolina. Granted, that place is larger than my 1100 sq ft but more bodies equals fewer square feet per person. In any case, my father rises before the sun, as gerontological quirks require fewer hours of sleep. I peeled myself out of the bed at what I think is a fairly reasonable hour (8:30ish) and went about my routine for waking. After visiting the water closet, I tottered into the kitchen to get my java, all while my cheery father was repeatedly saying good morning to me, and trying to ask how I slept, and other attempts at conversation. I kept waving him off with a grunt, much like my mother (and his wife for 33+ years) did any time he attempted to talk to her that soon. He either didn't get the hint or didn't recognize the gestures and noise.
My sons tried to tell him. My nephew tried to tell him. It was all to no avail. Finally my oldest said "Grandpa, for everyone's safety, do NOT talk to her until she's had coffee and speaks to you first. Seriously, it's dangerous if you try to talk to her before she is fully awake." My father responded with "ah, ohh-kaaay" with a hint of personal offense taken by my lack of desire to talk to him. The man watched me and as I tipped the mug back for the near-final swig, he tried talking to me again, asking if it was safe to greet me. I shook my head no. The coffee wasn't strong enough, and would require a second one. It made me very grateful that I was able to convey to my children the understanding of my quirks, especially the first-thing-in-the-morning deal. I didn't want to be like that, but in all honesty I just don't move fast in the morning.
Fast forward to today. My neighborhood association had a yard sale last week that was essentially rained out, so they quickly decided to do it again this weekend. I spaced out about it, even though i wanted to go scope it out, if nothing else to look at other people's clutter they were trying to pawn off on the rest of the world. Again I move slow in the morning, and slower when I'm not completely healthy. We ended up going over there as the last 3 people were packing up to go back home. My son the Beast, trailed along after the episode of NCIS he was watching ended, while Clone and I were already done. He snagged himself a couple 1000 piece puzzles (insert motherly eyeroll here) a PS2 game, and a mug. He came to show it to me and upon returning it, the mug's seller saw him with it and told him to just take it. He's excited about free stuff (it's genetic, my apologies). He brought it over to show me and yes, it rather aptly describes me in the mornings. But he's unwilling to let me have this mug, tells me to get my own.
