On the subject of phone number eitquette, here's another thing that I've had come up. Occasionally someone has asked me to give them someone else's phone number. I always decline. Typically I say that I just don't give out others' phone numbers. I might say that "I will give them your number and your request that they call you." It is almost never good manners to ask someone for a third party's phone number. Once, a relative asked me if I had the phone number of another relative. I said "No." even though I did have that phone number. It just wasn't my place to give that out. The person asking tended to be intrusive. I didn't want to inflict that on the third party.
