I had to wear a tie for many a year as my boss deemed a chap undressed without one. I bought round neck sweaters and wore my tie with the top button of my shirt undone and the ruddy tie pulled down, so you couldn't see it. After a year with nobody asking me where my tie was I left it off. Ten years later in that place nobody had noticed I wasn't wearing a tie. As my room was the coldest in the place, like Siberia in mid winter on a hot summer's day I had no reason to be seen without a pullover.
Since i left that place sixteen years ago, I've worn a tie for three funerals and a wedding. (Different one for the wedding in case you are worried.)
