After leaving Humble TX (where the reunion was), I drove to an IHOP in Houston to meet with my sister and brother-in-law before we went different directions to go home.
LOL! I now know why the chemistry teacher remembered my brother-in-law! He was at BIL's reunion two years ago and BIL spoke with him! I had not known this, and the ex-teacher said nothing about it.
Anyhow, I'm back home again!
