I'm fine with (something)

This phrase means that you're OK with something, or you don't mind it. For example:

I'm fine with that color.

In this example, the speaker doesn't really, really like the color. She might like another color better. But she thinks that that color is good enough.

You use "fine with" in statements:

Yes, I'm fine with that.

It's not usually used in questions. For questions, use "OK with ___":

Are you OK with this one?

The phrase "I'm fine with ___" sounds pretty positive. Another phrase with a similar meaning but a less positive feeling is:

I can live with it.

a traditional ceremony

A "ceremony" is something like a wedding, a graduation, or a funeral. There are also lots of different religious ceremonies for different religions. Ceremonies are formal events that have a strong symbolic meaning for people.

A "traditional" ceremony is one that's done in the same way that the ceremony has been done in the past. A traditional wedding ceremony for Christians living in the United States would be one where:

• the bride wears a white dress with a veil and the groom wears a tuxedo
• the wedding takes place in a church
• the bride and groom give each other rings, and have a kiss after the minister tells them that they're married
• there's a reception (a party) after the wedding with speeches, a little dancing, and a large cake

When people use the phrase "a traditional ceremony", they're usually talking about a wedding ceremony.
