I remember our first trip to the sea. It was wonderful, we were so in love... We kept holding hands… Each moment together was pure happiness. It is a pity that those holidays are over. Now all we have are memories... I remember our walks to the beach. The smell of the sea air, the warm sun on our faces… I even remember the song that was with us then. The memory of those moments is so moving… We were joking all the time, fooling around, we were so inseparable… It’s a pity that those days are behind us. They're long gone... If only I could turn back time, even just for a moment, and live it through once again… Our first vacation together was wonderful... It was so long time ago. Amazing moments, that won't come back...*

I don't feel like doing anything. It's terrible, I want to cry... He's trying so hard so we can be close together… He's wonderful! When I'm thinking of him, my heart is full of joy. We understand each other so well… I love spend time with him. We have so much in common. I love it when we listen to the music, walk together, plan our trips to the sea… We're so close to each other. He is giving me so much warmth and caring. I'm so happy that we have each other. I would love to hug him right now.
