Last night, I was getting ready for bed, and I felt some stuff in my belly button.. nothing new. I have an "innie" and it gets lint from time to time (always blue, I don't know why. I could be dressed head to toe in orange and yellow, and I swear my navel lint would be blue.. maybe the navel produces it's own lint.. hmm must research) so I go to retrieve the lint that has collected there in (you know, cause I'm all hygenical an stuff) and I pull some weird lint out and then my navel starts to hurt a little. Weird, belly-button pain is not exactly on my "hot list." I stick my finger back in there to sort of "check things out" and I have blood on my finger. Rather disconcertingly I am bleeding from the navel. Not one to panic, I go to the bathroom and swab out my navel with some rubbing alcohol and a q-tip. Producing a rather peculiar stinging sensation, and more blood, and then I just sort of left it alone.
I remember when my folks brought my brother home from the hospital. There was this big clothes pin looking thing on his umbilical chord. When my mother very scientifically explained what it was for (the cord, and the pin) I became very worried that the pin would fall off and that my baby brother would "go flat." Belly buttons are weird.
