10 years

Tu said: it's been 10 years. I counted with my finger phanlanxes: 6, 7, 8, 9, 10, 11, 12, 1, 2, 3; that's true, it's been 10 years. Time goes fast, i have friends who i've known for half, even for three fourths of my life (i'm 20). Feel so touched and incredibly lucky.
A few days later, i told him: i think about the future, in a few years from now, each of us will have our own job and be busy with our own life and we won't be able to see each other (i avoided saying that our group would break up), that'd be so sad.
He replied: for each period we'll find a different way of relating to each other, we'll keep different memories, friends will stay friends.
It doesn't sound untrue.
