They (and we) moved away not long after, and lost touch, :-( However, she'll always be in my heart! Why, just the other evening, I prepped 5 lb chicken tenders before freezing most! I'm pleased to report, "On a good night, it's nice to see I've still got it." (even living with RA)!
It's nice to remember my best mentor from down south (Montgomery, Alabama way), with the best lil' old accent "ya'll ever-did-hear." In fact, if she could hear me now, she'd might "just piiitch-a-fiiittt!" LOL!
