On the last day of high school, everyone was hugging and crying, and I just laughed at the thought of going to university again, and later I realized that I was wrong. No longer are we in our high school years. Sorry that day did not cry, sorry for not knowing it was the last time we met.
People often told me, graduated one is that friends have a few to dive and fall off "a lot". As time passes, we are no longer ours, our busy life, more anxiety, more relationships. All gradually "worn out" the old things, though not deliberately, but still no longer remember each other as the old days.
