Can I tell you something embarrassing? We've been on holiday for the past week - and drove back this evening. (Fantastic luck with the weather - so lovely). And... for three hours I sat in the front seat of the car, needing a poo. Eventually, I admited defeat, and asked DH to pull into Fleet Services (a Service Station on the M3 motorway in England) And I head off to the toilet... Lock myself in my cubicle... sit down and... Three hours of sitting squashed up in the car has made my bowel go to sleep and lock solid I can't push - and I can't go Ten minutes later, and I'm still huffing, puffing and panting, and still no closer to relief Another ten minutes later, and I'm having to drag my full bowel back to the car, to sit back in that front seat, and endure the most uncomfortable car journey back home ever!
