The Bank

So I'm walking into a bank today and I walk by this woman. She is talking on the phone in another language. I look at her and IMMEDIATELY the inside of my head starts playing dolphin noises. What causes this? I mean, I'm literally staring at her and at the same time,in my head, flipper is trying to communicate to me. When the foreign people hear me talk do stupid orangutan noises come out of my mouth (in their minds)?
