DH, SS and I went to a party on Saturday. SS's soon to be ex- step dad was there too. We hung with him a while because he didnt know a lot of people there.
He became friends with the host when my DH introduced them because the step-dad needed a sub-contractor for a job he was doing and our friend fit the bill.
Odd, but it went well ( DH is more than fine spending time with the guy....he just didnt want to be around his ex...and apparently the guy is finding out neither does he, considering he is soon to be her 2nd ex H. )
