moh speech for someone i don't really know

Typically the speeches are about the person, so I think you should try to personalize it as much as you can. Welcome her to the family, talk about the fun you had planning your weddings together, looking forward to a continued friendship as you adjust to married life.

Another idea is to do a “survival guide on being in this family”. My friend’s sister did that as her speech and it was sweet, funny, and helpful!

View quoted message I'd concur! a speech giving marriage advice would be a good way to go.

Are there any fun childhood memories you can reflect on? maybe talk about how glad you are that in recent years you've gotten closer and how honored you are to stand up with her at her wedding?

I don't know, this might be an unpopular opinion, but you're doing the toast to the bride, and and least part of it should be special, so I'd avoid being too "general", and risking it being too impersonal.

Fake it till you make it, yo!

You can do a more 'general' one.. so include thoughts for a good marriage and advice... or read a cute poem or story or something.

That’s a tough one, I think it’s nice when you welcome someone into the family and talk about how great of a match they are. What you have planned sounds good with thanking everyone especially the groomsmen and then the couple for allowing you to be a part of their special day. I think as long as it’s heartfelt it’ll be great!

What about a “Tools for a successful marriage” speech with custody/campy/corny props? You could keep it to about 3, then wish them well, throw in a quote and be on your merry way.
