Age is a factor to various things.
Being older than others brings the curiosity of a child to watch their behaviour... possibly with a glass of wine in tow (ironically- aged).
A little pup wants to crawl up your ego, they start to bite.
You don't judge or assume, you let them for a time being.
Moment passes and they are encouraged to repeatedly do it again and again...
You become more ascertain of the environment you are in
You miss your "appointment" with the beach to keep your perspectives in line and you bite back.
They don't like it, oh boy, they don't like it!
Leave the pups behind and enjoy your mature society who's egos don't behave like newborn vampires thirsty for blood.
Make the trip to the beach and rediscover your goals with her in mind. She is still with you, make her proud.
