Observation 3

I am guilty of saying words incorrectly even though I know its wrong, I can't seem to fix it... EVER. I have tried trust me. I have grown up my whole life say fingernail as "fingernell." My parents, brother, friends, and family all make fun of me for this and every time I have tried to fix this annoying habit I can't. If I concentrate on saying it and say it slowly then I can say it correctly but if I am talking normal then I cant say it right. So because I have so much difficulty saything this word along with toenail, I try to avoid them.
