Yeah ... that's me. I had 3 brothers ...2, 4 and 6 years younger.. we were at picnic. I was 18 or 19. They to pick me up and started taking me down to the lake to throw me in. At first I struggled and then I just stopped and calmly told them to go ahead. Throw me in and then run for your lives and be sure to give their heart to God because their ass would be mine. Well, they started talking about it on the walk down to the lake. I had quit struggling and talking. Just giving "the look". They put me down and none of them ever teased me again. Its all about perception.
Your mom had that ability I'm sure.
