Link between the mysterious man and Neil Green

At night after dinner, Lisa went inside her bedroom and started drawing something. Just then her phone started ringing. She grabbed her phone and looked at it, only to see Carl Black's number. Her lips curled upwards involuntarily and answered the phone "Hello."

"Have you finished your girly stuff?" He asked mockingly.

She chuckled and said "Yes."

After a few moments of pause, she heard from the other side of the phone "I have sent you some pictures of invitation cards. You choose and inform me, OK?"

"Thank you so much, Mr. Black."

"Hmm?"

"I mean... It is helpful. I will select and send it to you. OK?

"Good."

"En... You have been very busy with the engagement, right?"

"No. Wedding planner will do everything. I have nothing to do."

"Oh....is the guest list long for the engagement?"

"No. Only a few friends of Mack are coming. I didn't invite any of my friends and colleagues."

"Why?"

"They will come to the wedding."
