I could tell he wanted to get off the phone quickly
Do something totally opposite on what he expects. If you call him for help with something, say thank you and get off the phone as soon as you can. He will expect you to ramble on. It will get him thinking.
If he calls you for something...either let it go to voicemail and call him back at a later time (also makes him think) or answer his question and say you have to go.
Do a total 180 from what he expects.
I try to do this. I tried to end the conversation before he did and he beat me to it. We only talked for around 2 and a half min., I got to ask only a couple questions. Conversation went like this.
XH-Hello ME-xxxx? XH-Yea ME-I think I may have to trade my vehicle (its in his name). (I then explained why). XH-It's just your brakes. ME-You think so? XH-Yep, (the next part was said sarcastily) You probably need to get someone to look at em'. ME-O.K... then I asked about insurance on our house. XH-Insurance is thru xxxx and we have xxxx. XH-Well I'm gonna go. ME-Are you Planning on taking son out of town for his birthday (the reason I asked this, is because for the last few years they have went fishing for a few days for sons birthday. XH-I dont know yet ME-Well he wants...(I told him what son wanted) XH-Well I am not getting him that. ME-Ok, well Thank You xxx. Talk to Ya Later. XH-(said nothing, just hung up)
How did I do?
I dont have to worry about him calling me. He maybe has called me 3 times in 8 months. It was always me calling him.
