i did a mates nails the other day, a couple of days after she came and said that her index finger had chipped on the corner so i repaired it, a couple of days later it happened again on the same finger, now, when i had a good look it wasnt a break it looked definatly to me like it had been in the way of a sharp knife ( shes a cook !!!) i said to her to have a look at it and shel'l be able to see what i ment but she wouldnt have it she said it had definatly broken but i could see the clean, slanted, definate knife (or grated ! ) corner ! now my question is when someone does this to you do you argue the toss or just let it go ?
