1/ I called your number and your voice answered – “Sorry I’m not available. Please leave a message.” I put down the phone without speaking, and hoped you might pick up my thoughts.
2/ I called your number and your voice answered, sounding tired and lost. I wished I could hug you better, but the voice said, “Who did you want to speak to?” – It wasn’t you, but I still wanted to hug you.
3/ I called your number and your voice answered, and this time it was you. I said hello, and you said hello, but what could I say (that I wanted to say) that you didn’t already know? So we talked about trivialities until we said goodbye.
