Marital Status??

Today Jack had his 6 month well visit with the new pedi. As it was our first visit there we had to fill out all of the usual paper work and make sure all of the info they had on us was correct. The girl at the desk handed me a piece of paper and had me check it over for any mistakes:
Name: Jack Henry -check
DOB: -check
Address: unknown -check
Parent/Guardian: Jennifer -check
Marital Status: Single -oops
When I mentioned to the girl that there was a mistake and that I was infact married and not single her reply was "oh, no, that's asking about Jack".
So Jack's new stats are:
Marital Status: SINGLE
Height: 26 3/4 inches
Weight: 18 lbs 3 oz.
Head Circ: 43 centimeters
