I'm an old curmudgeon, but my manners are perfect, as is my interaction with other people. I never fail to say 'please', 'thank you' or to apologise when appropriate. I frequently apologise when it isn't my fault. If everyone was like me, the world would be a perfect place. Apart from the fact that you're not a curmudgeon (old or otherwise) you will be the same, which is one of the reasons that Lynn Truss's book ''Talk to the Hand'' makes such wonderful reading.
