My mom and my sister can sound exactly alike sometimes 😂

My mom has a deepish voice, while my sister’s normal speaking voice is even deeper. However, when my sister speaks at a certain pitch (speaking louder than usual), she really does sound just like our mom. They were both having a conversation with each other just now while my sister was consistently carrying that pitch where she sounds identical to our mom. I’m just sitting there trying to hide my laughter because if you didn’t look to see, it would sound like one person having a conversation with themselves. 🤣
