That's great you went to a T. They can be stressfull at first. the laughing, i'm sure they weren't laughing at you, the same thing happened to me on my first doctors appointment years ago, i still remember it because i got to be friends with her in the end of that session of my life. I think i had forgot my umbrella and every session she would remind me but i always left it for her, just to be funny and she understood it.
