When you first meet, you get over-excited and hug each other a bit too tightly.
Your very tight hug is followed by each of you telling the other that you look gorgeous.
Then you each deliver a 15 minute monologue updating each other on what you've missed.
At some point, the waiter will come over to take your order and it'll be a bit cringe because you haven't looked at the menu yet.
Of course, you always meet in the same place.
You both speak 950 times faster than normal human beings.
Eventually you start reminiscing over things that happened years ago.
You exchange gossip about all your old teachers.
And wonder what all your old classmates are doing with their lives.
You each list everything you know/heard/suspect about all the people you used to know.
At this point, one of you will get your phone out for a Facebook stalk.
Some of your classmates will have inevitably got married in the time you've been apart.
And some of them will probably have had children, which will make you squeal.
Of course, it won't be long before the inevitable question is posed: who'll be next?
You start talking about what your high school S.O.s are up to now.
You ask after each others parents.
And if you're staying at home, you have a little moan about your families.
At some point, your chat will get ~deep~ and you wonder how you got to be so old.
But then you look at how far you've each come and actually swell with pride.
You make plans for when you're rich and famous.
Conversation will eventually move onto love.
If one of you has a new S.O., you'll need to provide detailed descriptions of every single one of your relationship milestones.
Not that it's really necessary because you've both stalked the hell out of each other's love interests.
You laugh until your cheeks actually go numb.
And it won't be long until you're finishing each other's sentences.
And before you part ways, you promise never to leave it so long again.
