It's been awhile since I've played Sun Valley GC

Our Thursday golf group moved to Sun Valley GC today because both Iroquois and Shawnee had something going on.  I haven't been to Sun Valley GC for at least a year, and I'm not sure I played it at all last year. 
I don't care for Sun Valley GC much, but it was a nice change.  The weather was beautiful today, so it was nice to be out on the  course.
I didn't have a very good front nine, but had a good back nine.  So, my total 18 wasn't bad.  I shot a 41 - 36 = 77.  My par 36 on the back was with 1 bogey, 1 birdie, and the rest pars.  However, one par 5 should play just as a par 4 from the forward tees, and that was the hole I birdied.  So, really, I was 1 over, which isn't bad.
I found out today that some of the people are really upset that a few of us are playing from the forward tees.  I don't understand it myself.  Our handicap is established from that tee.  But, because I've been playing so well lately they've assumed it's because I'm getting that 5 yard advantage off the tees!  So, I'm moving back a tee.  If that's what it takes to make them happy, I'll do it.  But, I've lost a little of that good feeling towards our friendship.
