Getting the gang to believe Me

They were my Indian neighbours and we usually met in front of my house and played games in the compound surrounded by our houses. It was like killing two birds with one stone; having fun playing games and keeping an eye on my brother and sisters.
After lunch, mum left me in charge. As usual, I met my ‘gang’ under the tree in front of my house.
It is usual even to youngsters nowadays. They prefer to talk and consult their friends on many matters. It was also true in my case. I expressed and consulted my friends more than my parents. This was because they were always too busy and hardly had time to attend to and listen to us.
I started quite hesitantly, "Hey guys, you wouldn’t believe me.”
“What?” Guna asked.
The others echoed his query, “Yes, what happened?”
“Listen,” I said. “Last night, after the horror movie, I saw something.”
“What?”
“A ghost!”
“Joking. You must be pulling our legs.” Ravi said.
I quickly added, “No, no. It’s no joke. Let me carry on. Remember the guy who committed suicide under the tamarind tree.”
“Yes. What’re their names?” Gopal asked.
“Let me see. Chandran, was the name of the boy and the girl…Devi. Yes, Devi.” Guna answered.
Thaila asked, “Yes, you’re right. But why did you ask?”
“I haven’t finished. You see, on my way home after you guys had left, I saw them.”
Before I could carry on, Gopal interrupted. He said, “Are you sure?”
“Yes, believe me. I saw both of them.” I said. “The boy was hanging from the same tree and the girl was in front of me. She asked me to help them.”
“What? Help the ghosts?” Ravi asked.
“Yes, to help them get married.” I said.
“How?” Guna asked.
