I don’t know if it’s the sun, which is not only making more frequent appearances, but also seems to actually emit some honest-to-goodness warmth if it hits you in the right spot in the right way, or the exciting changes and opportunities going on in the lives of people all around me as they buy houses and take trips and anticipate the arrival of babies, or some other as-of-yet undiscovered but equally potent and influential factor, but I’m feeling adventurous, which is something I never feel, and a longing for the sensation of sand or cobblestones or grass under my feet, which is something I often yearn for but rarely picture quite so vividly, brown and grey and green, hot and hard and warm, familiar yet deliciously, tantalizingly, seductively exotic.
