You're right on that, Jo, because sometimes we pray, not really understanding what God's intention is for us in any given situation. He may answer "no" or "later" because He sees the big picture and we do not, so if our prayer is for something that ultimately will hinder or harm us or another, or if our prayer is not in keeping with His will, then He, in His love and wisdom will give us an answer that may disappoint us. (Just like a parent often will disappoint their child for the same reasons!)
We may think we know what is "good" for us and of course we know what we want, but there is a "good" and there is a "best" and that may be impossible for us to discern from our finite perspective, but God sees all.
