Even on the Phone

A couple nights ago, I was phoning my mother. I dialed her number, but didn't hear the ring tone. Instead, I heard the tones of someone dialing a number. I said, "Hello?" Then, I heard my mother's voice. "Hello, Sophia? Is that you?" "Yes, mom, it's me." She said, "That's weird. I didn't hear the phone ring and I was dialing you and you're already on my phone." We were both calling each other at the exact same moment.
