Signs - Reserved

I had a piece of string and tied it between the two stauchons along the front seat at 10 pm or so with a reserved sign in the middle. Had a couple of ladies riding wondering why it was there. Then boarded a semi regular passenger from the post office and i gave her my pocket knife to cut the string to sit there. The one lady said to the other, "Isn't that nice that he reserved a seat for her?" Too funny!
