I know this is closed and I cannot win a prize but I really like the question so I would like to answer it anyway without a chance to win.
The most memorable interaction I had here on STEEM was when @mariandavp sent me a BEAUTIFUL drawing of a starry night in Lisbon.. When I first got to STEEM I came alone. I did not have real-life friends on the platform, I came out of my own curiosity. I stumbled upon @mariandavp's page and we commented with eachother. Later I told her I loved one of her art works and then the next the I know, she shipped it to me! The moment I opened up the box I knew right then that STEEM is REAL and has REAL tangible value in life. I will forever treasure that piece of art, it was the first piece of a growing gallery! Thanks a lot @mariandavp! You are awesome :)
