I didn't see the episode, but I saw that clip somewhere. It hit home for me as well and like you said Sassy, it's part of the reason we don't tell anyone about ttc.
I'd like to see them follow the "infertility" storyline, but since it's a comedy show, I wonder how they'd work humor into the situation. I mean, there are some funny things that go with infertility, but they are FAAARRRR outweighed by the emotional and dramatic things. To be honest, I don't know how I'd feel about them making infertility funny if that makes sense...idk
