Make sure you use blue or BLACK ink!!! One time it was so funny (o.k.funny to me) Jim had a pen with GREEN ink. When he got to the lady she looks him up and says " Mr. JIM why did you use the green ink?" (irriated look here) he looked like a little boy getting scolded. LOL "Go do it again" LOL O.K. at the time, not so funny. you had to be there.
