was that my mom speaking to me?

so my mom passed on 5/13, 5/14 was Mother's day. I talked to my mom every day, probably only missed 7 days over the last year. My mom's name was Dorothy. last week, on 6/14, one month after Mother's Day, I called American Express. when the customer service agent came on the phone, she said... "hello Mr. Evans, this is Dorothy" The immediate thought that came to my mind was "mom? is that you?" then I lost it, cried like a baby I believe in some way, it was mom talking to me
