To anyone who has had the pleasure of a late fall morning standing lakeside, watching water birds awaken in the morning mist, I needn't describe the action and appearance of swans and geese as they "stand" on the water, stretch, crane their necks, and flap their wings.
A stick drawing would result in a figure very similar to the "fu."
To confuse matters, there are a number of other hiragana somewhat similar in outline. I will try to differentiate between them and provide examples.
