A Mistake On A Birthday Cake Box

Yesterday was my daughter's birthday. I bought a birthday cake. There are some blessing words on the box of the cake (or cake box), "Roses, sweet and fragrant, on this special day for you. Hope your birthday blossoms into lots of dreams come true!" While my daughter read it, I thought think maybe there was is a mistake in this sentence. It should be "Hope your bithday blossoms into lots of dreams AND come true!", they missed an AND there. Am I right?

(I commented on this already above, but because it is poetry and a saying "dream come true" it is correct as is.  but if you want to put an "and" in there it would be better to include something like "Hope your birthday blossoms into lots of dreams AND MAY THEY come true.)

What might (or will) would he buy bought?

Tom has been gone going shopping for a while and is about to come back (or return home). Tom's kids Jack and Susan were was waiting for him at home.

"What do you think he will buy for us？“ asked Jack.
"I think he may (or might) buy us some books" answered Susan.
"No, I think he will buy us snacks" Jack replied (in disagreement) disagreed.
"Let's bet on it!" challenged Susan.
"OK!"

A while later Tom came back with some books for kids (or children's books).

Susan (or delightfully could go better here) reported to her father delightfully about their bet:
"I thought you might (or would)  buy bought some books for us but Jack thought you would buy must bought snacks, so we made a bet and now it turned out (that is optional and could go here) I won!"
