Meeting my grade-school classmates has made me feel so utterly grateful that I never played the part of a complete jackass: not even while little. That saying about bullies? How they'll get their retribution? I think it comes back when the picked-on nerds grow up and no longer want to see or have anything to do with them.
The old saying: "Even a child is known by his doings" speaks to me every time I get together with long ago buddies who still shudder at the mention of a less-than-desirable memory's name.
