When you stop demanding an answer to 'why'.
Flipping through old photo albums.
When your birthday is just another number.
When going home matters more than taking a vacation.
When 'let's meet and plan' changes to 'let's plan and meet'.
When you realise that the grass is not greener on the other side.
