This has been an ongoing issue with ss33. He will get really close to DH when he wants/needs something then flee and not talk to DH for 6 months if DH is unable to meet a request. The entire time DH is moping and feeling bad that ss won't talk to him. Then suddenly ss reappears and needs to borrow DH's truck and all is good again like nothing ever happened.  Chase, disappear, repeat.
