Handicapped Parking Tag

Today I took my Mom to get her handicapped parking tag.  Of course she dosen't drive but we need one when we take her to the store or restraunt. They insisted that she have a doctor's signature that she needed one.  (Being 95 was not a large enough criteria.) The doctor signed that she had a permanent disability. (old age).  When she got the tag, the expiraton date was 12/21/17. I said to her, " did you notice the date?" She said,"Yes it's my birthday."  I reminded her the tag expires on her 100th birthday.
