Step 1 - With all of your might, hoist yourself up on to the couch. Look around and smile, because you are awesome.
Step 2 - After several minutes of hemming and hawing while trying to sit upright, roll off of the couch. Regroup by shedding a few tears and looking desperately at mama.
Step 3 - Hoist yourself onto the couch again, but this time don't look around grinning. PUSH! PUSH! PUSH!
Step 4 - Say fuck it and just act like you are sitting up on the couch.
