Good Things To Write In A Marriage Card Would This Be A Good Wedding Gift?

Would this be a good wedding gift? - good things to write in a marriage card

My husband and I have a friend who married this coming Saturday. You already have a shower, but were unable to attend, and we had no money (to give them something really, we are fighting to keep a roof). So we thought, because he will not give a donation, we do not go to the wedding. It is not an imaginary wedding. But then we believe we still can. But we will not only without showing them anything. I thought I had them, maybe a nice greeting card with a card purchase of $ 15 or 20 for an ice cream parlor - as Dairy Queen? (I do not know if) they sell tickets to buy - and write a note: "This is for you a romantic, if you can be treated together. This may seem insignificant, but the marriage it comes to small.. Is it ridiculous to her? "Like I said, we have no more than $ 20, give a gift, and I wanted to give a gift to someone else. I like the original. If this does not sound right, would you still Sugg originalthe Quaestiones (cheap, but nice)? Thank you!
