Hell, I could never do what I do, either. But I have to. My son is mine. I love him. I want the best I can do for him, like anyone else. There aren't a lot of other options.
I'm often exhausted and depressed. I'm not sure I CAN "do it" one more day. Friends and family could, for one day, stop exclaiming their praises over my heroics (or stop telling me what I should be doing) and give me a hand. Yes, people, you COULD do what I do!
Help someone out who has a situation that they didn't bargain for. Give them a break for one day -- or overnight.
Now THAT would be heroic.
