I Think I Eventually Can

I'm very particular about the use of the word "can't".  I hate it when a person tells me I can't do something.  That, literally, makes me cringe.  Every weekend, I have physical therapy at my house.  During my physical therapy session, I go on my treadmill with my physical therapist assisting me.  Recently, my dad has "upped" the speed on the treadmill to a relatively fast pace.  I think running is defined as having both feet off of the ground at a single moment.  Although my workouts on the treadmill feel very tough, I haven't quite reached the running pace yet.  So, although I will one day, I can't run.
