For Mom's 56th birthday, we gave her a gift certificate for a massage and facial with a friend at a local spa. When it came time to make the appointment, she decided to invite me along. In the car on the way over, I thanked her for inviting me, and said, "But I didn't expect this when we bought the gift certificate. I thought you would take your best friend." She looked at me with a smile and said, "I am."
