Life is like a train ride.

Sometimes we catch the express train and it's a quick, calm, easy journey.
Sometimes we get on that train from the 19th century: bumpy, noisy and slow.
Other times we stay a long time in the station waiting for the right one.

We meet lots of people that go on and off the trains.
Some, if you're really lucky, become friends, others just acquaintances.
Those who are amazingly lucky get to travel everywhere with their loved ones, while the regular folks have to wait for them, as they not always get to be close to the people that matter.

I'm a regular person.
Therefore I'll be waiting for you.
In every stop.
As long as my ticket is valid.
