Is My Bathroom A "Meeting Room" ?

Seriously, I can not take a shower without someone barging in or yelling for me from another room. Yesterday, for instance, was a prime example of how my bathroom is apparently the family meeting room. I went in to take a shower and shut the door behind me. I was enjoying my shower. Then, my husband came in to tell me about something he saw on the news. Why it couldn't wait till I was done with my shower I don't know. My daughter then came barging in to ask if she could get on the computer. (At this point, I was starting to get a little aggravated and because of this accidentally shampooed my hair for a second time instead of conditioning it.) I asked the two of them if they could please let me finish my shower in peace, about which time my son yelled "Mom.....!" from the kitchen. To this I yelled back, "Mom's in the shower!!!!"

Now, I don't know how common this is for most families, but I'm seriously considering hanging a sign on the bathroom door that simply states, "Meeting Room."
