Hot yoga

Tonight I am going to my first yoga class. Ever.
I am having some anxiety.
1) I might be too fat for yoga.
2) I am not very flexible. There may be only one yoga pose I can do.
3) What if that one yoga pose causes me to fart loudly?
4) Are people barefoot when they do yoga?
5) Is that the correct phrasing: do yoga?
6) If people are barefoot doing yoga, are they also neatly pedicured?
7) Am I going to have a hot flash while doing yoga?
8) Will I have a sneezing attack while doing yoga and pee myself a little?
9) Am I too fat to do yoga?

My first class is taught by a 30-something petite blond named Kat. She is a college-educated
stay-at-home mom of a toddler, a little boy with sky-blue eyes. Kat is smart and down-to-earth and obviously flexible. I mean, she's the teacher, right? She also has started her own business: designer landscaping.
Just this morning I sent her pics of my barren backyard. What do I plant here? I asked. And what about over there, in front of that huge expanse of siding?
She knows. Kat is a master gardener.
Tonight I'll find out if she's also a master yoga instructor.
She's certainly got her work cut out with me.
