Can I Just Go To The Bathroom?

Why is it that your family suddenly needs you when you are either on the phone, in the bathroom or trying to take a nice quiet bath? It is like they have radar that says "oh, mom is trying to do something that doesn't include us!" Like today, for example, I am literally just sitting down to go to the bathroom when my husband's phone rings. He yells up the stairs "Honey, do you have Tami's phone number?" "Yes", I yell back. Silence for about 10 seconds and then "Can you give me her number?" "Just give me a minute, I am in the bathroom" I answer back. Silence for a couple of more seconds and then "Where do you have her number?" I tell him it is on my cell phone. "Where's your cell phone?" "In my purse", I say. "Where's your purse?" he hollers. At this point I am thinking "Are you kidding me?" I just need one minute to go to the bathroom and I can't even do that in peace. He seems to be able to convey from my silence that I am not enjoying the hollering up and down the stairs from the bathroom so he says "Never mind, I will find it." After a less than relaxing minute in the bathroom, I come downstairs to check on the status of the phone number search. He seems to have found the phone number and is in deep conversation on the phone. All I can do at this point is laugh as I replay this little exchange in my head. Could it really not have waited for 2 minutes until I came out of the bathroom? The price we pay for our "I want it now" syndrome.
