An elephant never forgets.
There's some truth in that - elephants are amongst the most intelligent animals on the planet and have been shown to have a particularly strong memory.
Certainly one of the planet's most emotionally intelligent creatures, their behaviour shows indication of empathy and display of grief and altruism/sympathy too. They are adaptable, and they work as a team, they're loyal and self-aware.
So what better creature to represent our business?
