So up until a few nights ago, I've managed to do my "rinsing" without the girls seeing me. The whole process is kinda' disturbing, and I don't want to traumatize them in any way, so I've just done it when they've been in bed.
The other night I was mid-rinse when I felt a presence. I looked over, saline pouring out my nose, and saw Megan's horrified face. I quickly finished and grabbed a tissue.
Me: Uh, hey there.
Megan: WHAT are you DOING?!
Me: Rinsing my sinuses. You've never seen me do this before, have you?
Megan: No! Why do you have to rinse them?
Me: Well, it's to keep out ...
Megan: ... the boogers?
Me: I was actually gonna' say infection, but I suppose it helps with those too.
