i had absolutely no desire to go to mine. i really didn't love school and figured that if i had wanted to keep in touch with anyone, that i would have by now.
i honestly don't know if my school even had a 10yr one. we were a small country school and i wasn't on fb 4 yrs ago so i have no idea, and i moved away from there anyways.
my dh didn't go to his either because he is still friends with who he wants to be so it really didn't matter.
