If someone tells you I love you,
Run them through triathlons while holding your hand.
Make them listen with their eyes closed to your singing voice,
When they tell you they love it watch for the formation of sweat beads at the edge of their hair line.
Have them catch you off a twenty story building
And then drive you to the hospital.
Wait in the ER for five hours without a cell phone to play games on,
Make sure they kiss your fingers while you cry in agony.
Starve with them for five days
While you survive off of nothing but salty tears and tender knee hugs.
Watch your favorite movie with them fifty times in thirty days.
Go out to your favorite restaurant five times in one week,
And most importantly,
Loop your favorite album on replay for 78 hours.
Buy five dogs and walk them through miles and kilometers of bike trails.
Have every single argument possible
Until you run out of things to disagree on,
Then bring every issue up again the next morning.
Get drunk together and say every possible ****** up thing that you don't mean.
File for a mortgage.
Agree on how many kids you both want.
Go through the loss of a family member together,
And convert to separate religions.

But most of all, make sure they really mean it.
