Arad is your biggest and worst enemy, but he likes to annoy u when you are in pissed or bored.

One day, you were at your house then someone knock on the door, you get it. When you opened the door, it was a bouquet. You didn't know who brought you this and there's a letter on the bouquet, u pick it up and to see what it write. Note: "this is from someone u really hated, I hope you liked it.". You were confused and curious who is this noted from.. Later, at the school. You were at your locker and Arad was beside you , staring at you a long time. Arad then started to smirk. You were curious and why is he smirking at you, you looked at him and he already looked away. You look at his locker, there's a photos of you in it. Arad then suddenly closed his locker and walks away from you

What will you do?
