Friends after marriage

Your friends transform after they get married.

They get up very early, and goto work.
They come home early.
They bring a lunch box or they just go back to home during lunch.
They quit all social drinking. And non-veg.
They are not free to spend money like before. They would think twice, thrice.
They look more prim and proper with ironed clothes, and shaved beards.
They look more happy. Atleast in the beginning it is like this.
They look little bit restrained, and cannot say shit in front of their spouses.
If they visit you, they would leave early.
If you visit them, you better leave early.
You cannot watch PG13 movies with them, when their spouses are with them. They feel embarrassed.
They goto temples regularly.
They celebrate all things ritually.
They gives gifts to each other on birthdays or occasions. They never did before though. I feel embarrassed sometimes when I still go without a gift. I don't get it.
You cannot just call them anytime.
They tend to hang out with other married couples. Or just solitary.
