I offered to pay my T for phone calls after he talked to me for quite a while on the phone when my dad was in the hospital the first time. He told me that phone calls were something he just wanted to do, and he did not charge for them. Later, when my dad was dying and we ended up talking on the phone several times in a month, and I asked him to leave me messages I could listen to them over and over, I said something again about paying him for his time and he got a little offended. He said he was calling me or talking to me when I called him because he chose to and not because he was obligated to.
