Obeast tried to be funny with me at the gym I like my sneakers wicked tight when I run at the gym, so I'll tie them before I leave and then retie them right before I turn the treadmill on. This morning I got sandwiched between an obeast and a normal older woman. Obeast was about 350lbs and waddling at a breakneck speed of 3.2mph. When I put my right foot up on the siderail so that I could retie my shoe, he reached over and faked like he was untying my shoe for me and then grinned at me with his gross jack-o-lantern looking teeth. I tried to give him the most purposely uncomfortable smile/grimace I could manage.  What do you not understand about personal space? Yes, we're in a tight space, but the siderails exist to separate two treadmills. It's the same as arm rests on an airplane! You're not supposed to cross over! Oh wait....
