I have just spent a good 5 minutes weighing up the pros and cons of leaving a small window in our loft extension open. Pros: we get some fresh air but more importantly, all the highly poisonous toxins that MIGHT get into our house tonight - carbon monoxide, random nuclear gasses etc, can circulate and escape through the window thus saving us all from silent death. Cons: a very small serial killer could get up 2 ladders, squeeze in and slay us all in our beds.
Having decided to close it, I then had to shut the lids of the toilets so as to prevent a highly deadly snake, smuggled into the country by a local resident and currently lost in the sewage system, from slithering out to bite us while we sleep.
And finally I checked in the childrens beds to make sure they hadn't accidently fallen asleep with a pair if scissors under the duvet 
This is an average night's pre-bed checlklistI.
Is it just me? Am I completely off my rocker? Please say it isn't so.
