Sitting Backward

A blonde came home from her first day commuting into the city. Her mother noticed she was looking a little peaked and asked:

- Honey, are you feeling all right?

- Not really - the blonde replied.

- I'm nauseous from sitting backward on the train.

- Poor dear - Mom said.

- Why didn't you ask the person sitting across from you to switch seats for a while?

- I couldn't - she replied.

- there was no one there.
