Grrrrr

I went out to a chiropractor appointment this morning, then stopped off at Waitrose for Seville oranges, having called first to check they had some. I bought a few other bits and on getting back to my car opened the passenger door. Don’t know why but looked at the front tyre and noticed a slit of about 2-3 cm. I have no idea why I didn’t pull in at the tyre garage as I passed it to ask what they thought just drove on home very carefully to show OH. He asked me why I hadn’t called in at the tyre garage! I am a complete noodle. I’ve got a nasty habit of hitting the kerb as I park but obviously haven’t used the car in weeks so don’t remember when I could have done it. 
Anyone else feeling like a noodle today?
