My mother literally told me I cannot drive with my 2 month old to Missouri Due to it being "illegal" without all of her vaccinations...she has all the vaccinations she can have at the moment and its only from nc a 14 hr drive to see her father graduate. Who btw hasn't gotten to see her yet in person...only through videos...I knew it was a lie....but seriously u want me to stay that bad I'm only gonna be gone for 4 days. -_-
