What do you as an idividual treasure the most and find most valuable in a friendship?

What is it that really makes your friendship solid? What do you guys talk about, what stuff do you guys like to do for having fun? Name one moment you had with your friend where you couldn't stop laughing because it was so funny! How long have you known your friend? What qualities are the qualities of your friend that really make you treasure your friendship?

And if you still managed to keep in touch with that friend of yours even after finishing school, how do you still keep in touch to keep the friendship strong?

Any answers would be much appreciated!!!! Thank you!!
