Where is the another half?

aOne day, there was a customer talked about fish with me by a big fish pond.

"I kept many big fish in my home pond" the customer said.

"What’s your fish size?" I asked.

"Bigger than yours." He made a gap of about 16----18 inches between his two forefingers.  

"That isn’t just big fish, big money as well. You know the same size fish for sale in our pond about 400 quid each." I said.

"Yes! I know." There was obviously a smile on his face, he was a little proud.

"How long have you kept them?" I asked.

"About 10 years." He told me.

"You are a very good fish keeper." I praised him.

"Of course, I am! Did you know all of my fish were originally bought from you." His chest became a little bigger.

"They were our fish." I said.

"Yes! That’s true!" He put his thumb up toward me.

Both of us were laughing.

"I need another fish pond now indeed." He said.

"You can set up another fish pond by the original one then link up the two ponds together and make the water run from this pond to that pond like nature flow, the fish could swim from this pond to the other too. It should be wonderful!" I said by my poor English with the necessary body language.

"Yes, I will, but the problem is I have to move into a new house in the near future." He said.

"Don’t worry, you can talk with our manager and sent your fish here for a holiday, we will expertly look after your fish, after you settle down, you can come and take your fish back to your new pond " I said acted as a manager seemingly at the moment.

"Yes, good idea! But…" He paused and looked around.

"What’s the any more problem?" I eagerly wanted to know and try to help him.

"Where is my wife? Talking about fish, I forgot the another half, now I have to forget the fish and looking for my wife." He showed me a naughty smile, turned back and darted（突进，投掷） to indoor.

"Don’t worry, if you lost your wife go to the information desk!" I shouted to him as he has ran away.
