Must be at least once your carer has forgot about you? I hear some of these homes can be quite brutal at times.
One of my favourite solutions for showerless trips is baby wipes. They come with some sort of anti-bacterial ingredient in that moisture which completely kills any smell with a few wipes - and you can take them as hand luggage on a plane. See, you've all learned something today.
Whilst i wash often, my knob is still ridden with cheese.. I find the best option, is to pay some whoooore to lick it clean, but it's expensive.....maybe a **** and baby wipes are the way forward.
