When I went to the dentist when I was young, if I had a filling done I never got novocaine. I just had to grin and bear it. I never knew about novocaine until I was an adult. When you had to have something more serious done you got "laughing gas".
There was a grocery store across the street. One time I went into the dentist and mom went to the store. I was supposed to meet her in the car when I was done. I don't remember what he did but I needed "laughing gas".When I was done, I walked across the street to the car. At that time, you never had to lock your cars doors. I opened the door and laid on the back seat because I was woozy. As I was waiting for Mom to come out of the store, all of a sudden I noticed that the car seats had different material on them. I got up and realized I was in the wrong car LOL.
I was so grateful that the person that belonged to the car didn't come before I got out. How embarrassing would that have been ;-)
