Ive never refused someone, but I make sure they know when I want to go Im not waiting on them nor am I willing to spot them (I will as long as it doesnt require me to use any effort that will hamper my workout).
Yes Im a grouch at the gym.
He who dwells in the shelter of the Most High will rest in the shadow of the Almighty. I will say of the LORD, "He is my refuge and my fortress, my God, in whom I trust." Psalm 91:1-2
