superman is really tired (can't remember why, could be K or nightfall)

Lois is with him, and tells him to go to sleep, and he answers thanks mom, or okay mom when she helps in to go to bed and Lois is surprised to know that superman has a mom

thank you

Ooh . . . I'm pretty sure I've read that one before, but I couldn't for the life of me give you a title.

I think the story you are looking for is 'Blind Leading the Blind' by Pam Jernigan.

Irene

Or it might be Meredith's Night Errant

Sorry Irene, it wasn't it, but good story,
Thanks Kathy, that was the one....
