I attended my friend's wedding reception just to eat free food
So you just went there for the food? I hope you were invited at least!
I was happy to celebrate with them, it was not only for the food.
I am glad that you went there to celebrate too! It is important to share the joy on your friend's big day!
My friend seemed very happy to get married.
It is nice you were there for that event. Getting married is a big deal, and having loved ones there makes it a lot better.
