Out for breakfast after a rubbish morning

Some mornings I wake up and immediately have to use the bathroom. I would be trapped there for 30 minutes while the kids need to get ready for school, breakfast and packed lunch need to be prepared and the other half might want to follow the call of nature too at some point.

I don't understand why this happens. There is no relation to what or when I have eaten last the evening before. Also it doesn't matter how the night was, if the kids were ill and needed attention at 2 am or slept peacefully through the night. 

Some mornings are just like this. So today I am extra hungry, which leads us to our favourite café again. Let's see how this works out, usually if the day starts like this, the rest of the day is not very easy on my digestive system either.
