You are here
Here is an idea:
OMG!!! I have been wanting to talk to you for so long..... why haven't you called?!?!?!? Well you're capable of knowing that this is a voicemail machine. I'm so sorry I cannot reach the phone right now, so if you could just call later and/or leave a message. I might not call back because I'm either too busy, annoyed by you, or just not in the mood to talk, so bye!!
