When wearing socks with your sandles or Crocks just makes sense, regardless of looks.
When you tuck your polo shirt, your wife purchased for your 40th, into you cargo elastic waist with drawer cord shorts.
When you pin your club or association badges on your hat.
When you get those flip up sun glasses lenses on your reading glasses, because you can not justify another pair of sunglasses.
When you run standard tyres on your 4wd, because only young blokes run larger tyres.
