Invites - to post or not to post?
I was talking to my sister today (who is my MOH) and mentioned that our wedding invites are now done. I said that when she is at my house in a couple of days I'll give it to her. She seemed really shocked that I wasn't going to post it to her. I didn't really see the point as she only lives 5 minutes away and I would be seeing her in person anyway (before it would arrive by post). I said that I was planning on giving most of the guest their invites in person or popping them through their door as they all live locally or I would see them quite soon (there's only a few as it's only a small wedding party, going abroad). Is this a bad idea?
I get that it's nice to receive something formally through the post but they kind of will if I just post it through the door, why do I have to pay for postage and make them wait? Also we're not having a very formal wedding so why have a formality like 'the invites have to be posted'? After how she reacted and the things she said I feel like I'm comitting some kind of wedding faux pas!
