Have a wonderful Holiday, Louis!
You've already shown how tough you are by having your lemonade while your mates did their thing in the pub.
The opportunity to have a holiday with your parents--sober!--is something I look forward to.
With them living a few states away, and me only going home for weddings, reunions and the like--I doubt they know what I'm like sober anymore. Can't wait to show them!
Travel safe, and stay strong.
