I use a dog whistle ringtone on my phone.
“Dogs barking: I have a call.”
note: it’s too high for you to hear.
double note: the outer part of your ear keeps growing until you die: do you really want to live forever?
triple note: who would call their kid “Ear nest“?
Today I thought my hearing was getting bad while talking to a co-worker, but it turned out that I just wasn’t listening.
(I’m just tone deaf when people strike a certain tone with me) hee hee!
