To the I, Anonymous "I don't want to fucking smile for you"...You could not tolerate an old man asking "Why don't you smile?". With all due respect to your recently departed friend, chances are good that old man has endured the loss of many a friend in his old age. You bemoan his glance at your cleavage and whine about enduring jokes and smiling at patrons in a customer service position. One can only imagine the psychological scarring Arnold Schwarzenegger has endured over the decades from female senior citizens leering at his biceps. In light of your indulgement of self-pity, it isn't hard to surmise your cleavage might be one of your more endearing features.
