Things that are easier with two hands.
Here's a list of things un-slinged people take for granted:
-typing (currently 'pecking' with my right hand)
-eating on the couch (note: measuring cups work well, the handle is easy to hold onto and limits food intake or maybe it doesn't)
-opening jars of peanut butter (warning: this may cause reason for emotion breakdown)
-dressing myself (includes buttoning pants)
-texting
-washing dishes
-sleeping (trust me, when you can't lay on your side or move due to a sling, its hard)
-erasing my mistakes on a statistics test
-folding clothes/blankets
-icing cakes (I haven't actually tried to ice a cake but I can assume)
-washing hair and shaving
-tying shoes

Note the massive black contraption that is called the 'ultra slinger' that adorns the left side of my body, it comes with a velcro cell phone pouch and an exercise ball.
