Bahahaha...you ladies crack me up! Sandra - I do the same thing. I'm an emotional wreck most of the time and I will bust into tears randomly (mostly because something has been on my brain for awhile and then I break down and cry about it). DH is kinda used to it, but it's awesome just saying it's because I'm pregnant.
Although, it HAS gotten a little worse. I totally bawled at the Folgers Commercial that's coming on now. A guy gets home from West Africa and his sister opens the door and is soooo happy to see him. He gives her a gift, she takes the bow off the gift and sticks it on him and says, "You're my present this year"
And then I cry.
