Rita, I am the mother of the groom, and there is the wonderful father of the bride, and that's it. My ex-dh plays no part in the life of his sons (his choice about 20+ years ago), and Kerri's lovely mum died very suddenly and tragically of a brain tumor about three years ago. So, Kerri's dad and I will be 'paired up' for everything on the wedding day, and we both feel comfortable with that. We find it very easy to come together as one family, but we will all miss Christine on the kids' wedding day.
So, back to the old hat: It's totally up to me. I'm not going to stress. I'm going to spend a few days shopping. If I find a hat that I like and that doesn't look silly, I'll wear one. If not, I'll go without.
And to get back to "The Event of the Year": It's a shame we can't adjust the topic title because it should now read: "Just 2.5 more days!"
