Why must wedding invitations be addressed like the guest is being summoned to a 1943 boat or fairy or garden party? I shall address mine myself, with own handwriting,  which is just as nice but just a touch more ‘middle schooler decides to become serial killer / sends threatening murder notes / but is also kind of in a hurry and is probably drinking coffee and or wine while writing it so just except one of those liquids to make it onto the envelope,’ but mildly legible.
