SZN's mom liked SQC's "dad" when they both attended the same college. Unfortunately, SQC's "dad" liked her friend (the wife he married).
SZN's mom and SQC's "dad" attended a college party, got drunk, then did the deed.
SZN's mom woke up first, and left, then dropped out of college later. SQC's "dad" had no idea what had happened.
SZN is older than SC by some months.
