I just saw this and am so sorry to see that your Mom has passed. I vividly remember her from my days at Sentry in the late 70's. I know that was a long time ago, but she stands outs. I always enjoyed conversations with her when she'd come in.
Sending my condolences,
I also remember her quick wit - sticking it to us young guys - and following it with a laugh and a smile.
I am sure that I have forgotten a lot of what she said and what she did but I will always remember how she made feel. I always felt welcomed and invited into the Zastrow home like I was part of the family.
Rest in Peace Lois. I look forward to sharing some stories and laughs with you when our paths cross in heaven.
