Could you tell me a time you felt happy?

What I was thinking about doesn't really relate to happiness, but that's partly because I have struggled with the word happiness. I don't know what the word happiness really means. But I can tell you about a time where I was very contented, calm and it must be important to me because it's a recurring memory. I keep coming back to it at times when I think of things to relax and calm me. When I was in my late twenties, I was in my first job which had a high level of responsibility and stress with it. Every year we used to take a two week holiday and I used to take the first week just trying to relax. Often times the second week was the week I got real benefit from the holiday. I remember we were having a holiday in the Greek islands, I don't remember which Greek island it was but I do remember getting up early in the morning and walking from the hotel we were staying in up a track overlooking the harbor and the town. It was a beautiful hot summers day and as I sat next to a water trough, looking down at the scene in front of me. I hadn't seen anybody else and in the distance I heard a bell and as I sat there an old man and a donkey came towards me. All I could hear was the sound of this bell gently clanging on the donkeys neck. The old man and the donkey just came up the hill and passed me. The old man didn't say a word but he acknowledged my existence and then he walked off quietly without a word. The only thing I remember is just feeling very calm, relaxed, enjoying the view and having that person entering and leaving my life. I must have been very stressed in the lead up to that holiday and I think that switch from being very stressed out to being relaxed, calm and appreciating everything I had in life, turned on that walk I had on that morning. The imagery is something that I have returned to over the years. A moment which would be insignificant to most people is important to me as it is a recurring dream. And if I want to relax I can always close my eyes and think about that small fragment of my life.
