Rain. An unusual occurrence for San Diego‚ somewhat of a “glitch in the system.” The weather may have been warm‚ but the sky told a different story. It spoke with a dreary‚ gray tone‚ swallowing up the sunshine that regularly enlightened the sky each day. The rain pelting to the ground was more foreign than the absence of the sun.
