I know that feeling - well. You also want to pass on how you felt about the holiday to everyone else. everyone says did you have a good holiday but they don't really want to know. All the time you are bursting with it.
Sorry not doing much to cheer you up am I
The only cure for me is to start planning the next one.
I miss the grandkids and want to get home sometimes to see them.
I often wish when I am in Thailand that i could have all my friends round me and then I could share it with them. You can't convey sounds sights and feelings the same can you?
You are starting on a new chapter now - new job ?
The summer is on it's way and that is always a good thing.
Come and stay with us for a weekend when we get back. We will cheer you both up - or get you so pis-merry that you will forget you were fed up.
Or sod it , book a flight and come back and to Samui with us.
