My silly little fear

I am probably going to get grief for my silly story but I will tell it. 

My two biggest fears are confined spaces such as elevators and heights.  Yesterday I got myself into a situation with heights.  There was a staircase with a wall on right and nothing but a tool cabinet part way up the left side of this staircase.  I am walking up the steps and I get to the spot where there is nothing to the left.  My legs just stopped and I could not move for the life of me.  I knew that I would not fall but I was not balanced and that was what was making me nervous.  So if you want to give me grief in the comments, go ahead, I won’t stop you.  I was letting my mom and uncle tease me about it. 

Now on a completely different note, when you say thank you how do you say it? Thanks, thank you very much or Thanks much.  At the library I keep hearing people (mostly men) say thanks much.  So how do you say it or what do you say? Let me know in the comments.
