Luck of the...... More like Sod's law!

I have been busy this morning n been up early for a run. Just on the way out to my spin class. Grabbed purse, phone and then keys. The car was MOT'd yesterday so I took the house keys off, went for my run n when I returned I locked the porch door out of habit. I am currently sat in my porch with a set of keys that do not open the front door or the porch door. They will get me into my mum n dad's house no problems but not out of my own porch. Luckily I have a lovely dad who is on his way with their set of keys. My keysrings have shamrocks and luck of the Irish on them....didn't do me much good today.
