” I sent you the invitation months ago,” through your email.
Just because you can purchase paper plates and silverware, it does not mean you do not need to own real one. You can take pictures on your phone, it does not mean that you don’t need to print out picture again. Because you can send out emails and texts; that does not mean you never make a phone call again. E-viting does not mean you should never send out invitations. What is proper and personal mean these days, if you send it via email or text?
Do you save memories of the special thing like the pictures that you hang on walls. Your brain holds thoughts, that is not as good as writing a note that you can refer to. We have e-mails that pile up, then you delete them and spam for the things that your computer marks as junk. If your invite to a special event went in there would you notice before you click delete. How many spam things do you look at prior to deleting?
Personal is personal, use email and invitation as they were meant. Don’t let in invitation be considered junk.
