The fact that elephants are expected never to forget anything can make impending anniversaries for male elephants profoundly stressful, and been shown to lead to anxiety, depression and drug use. This elephant (pictured) is addicted to tranquilizers.
Anniversaries are great. If you can keep someone from working out who you truly are for an entire year then you deserve a bit of a romantic celebration. Sadly it is becoming increasingly customary these days to spend your anniversary with your partner and not with prostitutes, but traditional values will come back into vogue, don't worry. Another war will see to that.
