What do you think about counting monthly anniversaries together after so many years?

My cousin’s friend on facebook is always saying “Happy Anniversary” on his status so I wrote, “Hmm I could’ve sworn you said this 3 times in such a short period of time or maybe time just flew by! lol!” He said, “Monthly anniversaries…DUH.” I put “Haha, didn’t know after so many years together you guys would still do that.” His wording seemed as if he was offensive he said “Everyone else in the world counts it except you.”

I don’t think it’s necessary to count monthly anniversaries and say, “Happy Anniversary baby I love you!” each month. They’ve been together 3½ years. I stopped after a year hehe, but I don’t celebrate each month we’re still together
