Childlike Faith: We'll See

Do you ever catch yourself opening your mouth and hearing your mom come out? It happens to me all the time. My favorite phrase that popped out a few months ago was "Well, if you'd quit counting the bites and just eat them, you'd be done already." Yep. Heard that a few times growing up.
One phrase I used to swear I'd never use on my kids comes out all the time, though. Want to know what it is?

"We'll see."
"Possibly."
"Maybe."
I used to hate it when my mom said that because I figured out that more often than not, it was going to be "no" in the long run. And yet, when my children ask if they can do something, what do I say? You got it. I say one of those phrases more often than not.
My children, though, aren't quite old enough to know that it's probably going to end up being "no." Instead, they look forward to it turning into a "yes."
"Mommy, can we play with playdough when we get home?"
"We'll see."
Squeals from the backseats.
Hmm. But it got me thinking.
"Maybe" is sort of one of the answers we get when we pray. God never doesn't answer a prayer. Sometimes, He just tells us "No" or "Not now." Of course, we don't really know which one of those answers we're getting until the door has completely slammed in our face. So, how do you handle it when you get one of those answers toward something you've prayed for so hard? Do you react like my children and squeal thinking it will happen later? Or do you react like an older child whose hopes have been dashed too often and simply give up earlier than you should?
I'd say, before my husband I went through infertility treatments, we probably gave up more often than not. But after waiting for six and a half years, continuing to pray the same things over and over, we're a little better at keeping up at least a little hope while we wait. I know I'd rather be like that. How about you?
