I was reffing an under 12s game with club linesman. Blue attacker was 5-6 yards offside (I could clearly see it was offside) when a ball was played over the top. He chased it and the defender chased behind him but I waited for the linesman to give offside. About a yard away from the ball the attacker stopped and left the ball (realises he was offside) and the defender also stopped but he assumed offside had been given so he left the ball. Then a different blue attacker came and got the ball (he was always onside) but after a few steps he also stopped thinking offside had been given and he kicked the ball to a defender. At this point I had given nothing and the linesman hadn't signalled offside but I blew for it as everyone had stopped expecting an offside (which I believed it was) but the linesman said he never interfered as he didn't touch the ball.
