Reflecting upon events from this past weekend, I realized that I had picked up an unexpected habit. When my nieces are around, I call my father “grandpa”. I don’t just say this when talking with them, I use it when talking to my mother and sister. I don’t particularly remember referring to my mom as “grandma”. It probably happened but I’m not really aware of it. Whenever I was talking to my father directly, I would call him “dad”.
