STD's

so my mom came up with a good idea. since FH & I send out christmas cards anyway she mentioned that we should said the STD's with our chritsmas cards. we realize that it will be 16 months before the wedding but we really don't talk anything wedding with anyone. plus my mom thinks that thing will be very crazy starting in may (1 year before the wedding) with me graduating & looking for a job & my sister applying to nursing school. we have our list all ready so i don't see the harm in doing this.


is this just way too early???
