Where is my Wallet?

He looked so confused and walked back and forth there. I wanted to ask him why but, i saw that he didn't wanted to talk with anyone. " What happen with him, Nis?" I asked to Nisa, his next friend.
" I thought about his wallet was stolen by someone". Nisa answer.
I nervously asked ine more time to him, "Hey, what happen with you?"
"Someone steal my wallet at the street. He took my wallet when I still waited the bus." he said and sigh heavily.
I gave suggestion to report it to the police officer. He looked restless. "If you report it to the police, I'm sure you will know who is the thief." I said to him. After walked back and forth, he was sit uncomfortably in a bench. He sit beside me. He looked at me full of hoped. I try entertained him when he was sad.
"Really?" he asked. "But i think that's not a good idea," he continued. I was staring at him right now. "Maybe" I answered. He shift to another position, still not real sure what he wanted going to do. And he sigh heavily again. But he didn't looked confused anymore.
Finally, he reported it to police officer and one day later the police called him. He needed our helped to go to police officer. We accepted it. But i saw something wrong with my friend, Nisa and Edo. Their face looked full of smile and happiness. I just thought that our friend, Leo was so confused, but they looked happy.
After arrived at police officer, we met the police. He said that your friend, Edo, who steal his wallet. Leo and I was so shocked after heard that. I looked at Leo and say, "Why?".
"Hahahaha, did you forget guys? yesterday was so important day to Leo." Nisa said. Leo started smile and wanted to laugh but i know he got angry with Leo and Nisa. "Oh my god! Happy birthday my cool Leo!!! Hahahaha..." I remebered, testerday was Leo Birthday. We went out from police officer and took the birthday cake in Edo cars. I thought, it was his memories birthday that he couldn't forgot!.
