I had one thought as I headed to the beach for a 20-minute power stint of sea glass hunting and it was , " I got to get purple sea glass . " Well , there were a few thoughts . " Maybe there will be a big purple , or a dark purple or many small but varied shades . I hope I get some purple . I could really use some purple .

Question: Why could I really use some purple ?
