I think your mom and my mom must have been clones. One time at a Catholic funeral, (mom was Presbyterian) she asked one of the many Fathers present at the reception following the service, well if he's a Father (pointing her finger) and he's a Father (pointing to a different one) what do you call him? (pointing to a third) The Father cracked me up with "We call him Dad."
LOL! That reminds me of the time mom went to a Catholic church. At the end of the service at this particular church people would shake your hand and say "peace be with you", only mom was shaking hands and saying "pleased to meetcha!" My sister, who had married into a catholic family but wasn't catholic, was mor-ti-fied! I thought it was funny!
