last weekend I spent more time in the sun than I have in a while... walking and biking. Because I hate to be bothered with stuff, I didn't bring water, or wear a hat or put on sunblock, all the recommended precautions that we now must take before going out of our climate controlled dwellings. (I did wear a helmet, mostly because I leave it on my bike, so it was not a big deal.)   I am old enough that I remember just going out to play, entire summers spent laying in the sun, and turning properly brown while I read book after book after book, taking breaks to throw myself in the water to cool down, then going home to lay in a hammock and read some more until supper magically appeared..  Recalling it, I wonder if I actually lived through my own childhood  (idyllic until I hit puberty, after which idyllic let itself go and bloated out into  boring.) or whether I just view it through a hazy glow of golden nostalgia.  Nothing was that big a deal, babies sat on their mom's laps in the front passenger seat, while dads drove and smoked, flicking their cigarette ash out the driver side window.  In any case, this weekend, I threw myself back to those days and went out and about with as little fuss as I could manage. Problem was, I think I nearly fried my brain. It took me the whole of Monday to get a grip on my thoughts.  I ended up in the wrong place to meet my afternoon class (they went to the right place, actually read and followed directions!) got everyone's name wrong and went out like a light when I dragged myself home from work.   The next day was better, and it dawned on my that I might have been suffering from de-hydration. Maybe it was something all together different, but from now on, I will bring H2O with me. I will have to be my own  modern mother.
