Michael Sam's dad*Birthdays are always good for memorable stories.

For Michael Sam’s dad, his birthday came with a text from his son saying he was gay.

“I told him, ‘Well, you could have wished me a happy birthday first,’” the elder Sam, who has the same name, joked to NBC News.

Although he was surprised about his son’s revelation, Sam’s father fully supports the athlete’s decision.

“I was shocked because I didn’t see it,” he said. “I mean, you see your kids, but you don’t suspect that.”

“He sent me a text first,” continued Sam’s dad, who revealed that the message was simply “I’m gay.”

Soon after the text, the men chatted more about the confession over the phone as the 55-year-old patriarch received confirmation from the younger Sam that he was sure about coming out to the world.

“I asked him about his career and everything, and he said he was just going to do it,” the father said. “And I said, OK then. He’s in control and he’s grown. No matter what, he’s my son and I still love him.”
