I refused to shave off my various forms of beard for any of my three sisters weddings. Although, after the first one it wouldn’t really have been fair to do it for the other two. I did make sure it was nice and neat though.
There won’t be any passport issues either; my pic makes me look like a terrorist and I got in and out of Australia (twice), New Zealand, Hong Kong and China with it. I’m actually going to miss that dodgy pic a little when I renew this year.
