Naked birthday

On his Birthday, a man named Peter was really upset because none of his family members or near and dear ones wished him.
As he walked into his office, his secretary Anna said, "Good Morning Boss, and by the way Happy Birthday!"
He felt a bit better knowing that at least someone remembered.
At lunch time, Anna knocked on his door and said, "You know, it's such a beautiful day outside, and it's your Birthday, why don't we go out for lunch, just you and me."
Peter happily agreed.
They had their lunch but on the way back to the office, Anna said, "You know, it's such a beautiful day... We don't have to go right back to the office, do we?"
Peter replied "I suppose not. What do you have in mind?"
"Let's go to my apartment, it's just around the corner."
After arriving at her apartment, Anna said, "Boss if you don't mind, I'm going to step into the bedroom for just a moment. I'll be right back."
"Ok." He nervously replied.
She went into the bedroom and, after a couple of minutes; she came out carrying a huge birthday cake... Followed by his wife, his kids, and dozens of his friends, and co-workers, all singing "Happy Birthday".
And Peter just sat there...
On the couch...
Naked!....
