Because I was born before you I board the spaceship while you remain on Earth.
We both continue revolving around the sun but I do so at a sizable fraction of the
speed of light.
While you wait in line at the DMV I pass through the two-dimensional doorframe
leading out of sleep. While you suffer a season of winter I witness just six days.
When I land we are the same age & we are the same age all the days of our lives.
When we die we die of old age at the same time, holding hands, on the count of three.
