I had a close shave not so long ago...
Before leaving the SPs flat I had a shower and thoroughly washed to ensure that I was spotless. I also checked the bathroom mirror to ensure that I looked spick and span before leaving. On the way out of the door we had a parting snog then I disappeared into the night with the usual cheesy grin.
On returning home from my "late business meeting" the OH was busy pottering about, we exchanged pleasantries (from a distance without close contact) and I was informed my dinner was probably burnt to a crisp in the oven. Just to be sure that I was looking "normal", I visited the loo before siting down to my burnt offerings.
After dinner I moved to the lounge and me and the OH sat chatting and watched a bit of TV together. After about an hour or so I needed to spend a penny so I visited the loo again. The loo was occupied so I had to use the second bathroom, which is nothing out of the ordinary. However, the second bathroom has really bright lighting and large mirrors. As I stood washing my hands I glanced in the mirror, and holy fuck, I just about crapped myself, the side of my face from head to chin was all sparkly in the bright lights.
It would appear that the SP must have been wearing some sort of sparkly moisturiser which must have transferred on to my face when we had our parting snog.
Just as well the OH didn't cossy up to me on the sofa as I'm sure I would have been rumbled. I've absolutely no idea how I would have explained my way out of that one!
