This is really trivial but I wanted to know if anyone else has ever done this

I have always from the minute I was born loved to "sniff" the corners of shirts you know the end of the collar where the shirts are pointy??

Anyways I do it with anything now a days with a corner. I love my rain coat as its got loads of corners. I dig my fingers and nails into them and get a wee sensation in my fingers or nails its actually quite nice. If I haven't done it in a while I SEVERELY do it. My Mum says I have always done this.

Its pretty weird I guess!!
