I've been to 2 weddings and the bride and groom never came by to say hello to their guest. Honestly, as a guest, it makes you feel unappreciated. One of the weddings I went to the bride and groom didnt even thank the guest for being there. If time allows I hope that me and hubby are able to go to each table (total of 10) for atleast 2 minutes and say hello and thank you and take a quick group photo.
