(You are someone close to Tunner)
It was a normal day like any other, you were walking until you saw a hat flying through the air that ended up on the branch of a tree. It took you a little while to get the hat off that branch but you did it, you looked at it for a few seconds and realized it was a cowboy hat, ¿and who else wears a cowboy hat? Tunner.
You looked around as you walked and saw Tunner sitting under a tree without his hat on... He looked kind of sad (literally because he lost his hat). First you hid the hat behind your back, you approached Tunner and asked him what was wrong:
Tunner:"I lost my hat..."
You smiled warmly and suddenly put Tunner's hat on his head, he was surprised at first but when he realized he smiled back and said:
Tunner:"Heh... Thanks" He started to blush a little.
