I hate it when the phone rings. It only rings 3 times before it goes to voicemail, but each ring is like nails on a chalkboard. It always startles me (hyperviligent) and frankly I don't really like talking on the phone unless it's my sister or one of my few select friends.
I can't even tell you how many numbers I have blocked. There are days when I don't want to talk to anyone, not even the cats. The ones that count understand.
