it's my life

A young bridal couple go to their Hotel for their wedding night. The next day, the
bride's closest friend comes over and asks her how last night went.
She replies, “I'm just so tired! All night long it was up and down, in and out, in and out.
Don't ever get a room next to an elevator!”
Who is cheating who?
Wanting to find out if both his wife and his mistress were being faithful to him, Gary
decided to send them on the same cruise and question each one later about the other's
behaviour. When his wife returned, he asked her about people on the trip, casually
inquiring about the passenger who was his mistress when she mentioned the woman.
"Oh, that woman slept with nearly every man on the ship!" his wife reported.
Unhappy with this information, Gary planned a rendezvous with his cheating mistress and
decided to question her about the trip before confronting her with what he knew. Once
again, he carefully inquired about the woman who was his wife after ascertaining that
they had met.
"She was a real lady," his mistress said.
Gary's spirits picked up. "Why do you say that?" he asked.
"She came on board with her husband and never left his side."
