Tonight, while eating a pre-dinner snack of frozen peas...
Maddie: I think a pea came out of my nose.
Me: I don't think so. Unless you put one up there - DID you put one up there??
10 seconds later
Maddie: I think there's a pea up my nose.
Me: How did it get there? Did you put a pea up your nose? You're too old for this...
Maddie: I didn't. Maybe Katie did it.
In the end the pea was too far up for any kind of extraction - and while trying to get her to blow it out (while blocking the other nostril) it disappeared. I think she may have sucked it up so high it went into her throat. At least I hope that's what happened. I don't see it anymore...
