Please don't think I am ignoring your messages, I am almost certainly the least experienced PPL here and I know that I have an almost infinite amount to learn. But I like to think I am pretty good at visualizing where I am relative to the 'landscape'. That comes from many years in charge of large boats. Nevertheless, I don't have an accurate running fix in my head and if someone gives me a position and direction of flight I felt it would be useful to know if they were ahead or behind or were likely to cross from left or right. But it seems that I am overthinking this, thanks for your inputs.
