U can choose not to goHuh ....actually those JC, poly, army or uni frens that you've made but subsequently drifted apart coz all of you were busy establishing your careers and building families.
Rest assured, you will reconnect with them again. When reach 40s and 50s, many parents will uplorry and you will receive regular text msgs out of the blue asking you to attend funeral wakes. That's where you will meet up with your old frens, again. It feels like reunion actually.
