What's wrong with pigeons? They are bold, resourceful, varied, adaptable and sociable? They are useful, they can carry messages, they can take part in races and you can eat them. Flamingoes are pink and sort of pretty. Meh. I'll stick with the pigeons.
When did people stop opening doors for for others? When did people decide that being kind to others was no longer fashionable? The more unconditional "favor" you put forth the more you will get back. The key is to expect nothing in return for a good deed.
