Hallmark has a new line of cards for "family matters," including... infertility.
Second one.
Cover: I wish I could make things happen for you the way you want them to. I know how much a child would mean to you.
Inside: I'm still hoping and believing for you...and keeping you in my heart.
It's a perfectly nice sentiment (especially compared to
some of the things people say), and I know people so often don't know what to say, but seriously? If that showed up in my mailbox I'd probably either burst into tears (and not the good kind), or fall over laughing. Either way, probably not the response the sender would hope for.
