I went parachuting and had to pull my secondary parachute due to a malfunction in the first. I was FREAKING out.
That would be so scary! Did it work on the first try?
It did! That's the first thing that came to mind right before pulling it; "PLEASE let this one work!".
I can't imagine. Are you planning on going parachuting again? 
I think I will, but it'll be a while before I do!
