Sometimes it can seem as if there is an 800-pound gorilla in every grove. But not to worry, they are very easy to outrun. And - should you happen to trip - ferocious as they may appear, chances are they will just pick you up, dust you off and, pleased at having scared you out of your wits, treat you to a bout of their alarmingly raucous laughter. It is probably best in such a situation to just give them a quick hug, sheepishly shrug your shoulders, and explain that you are late. They pretty much always will understand.
