A recommendation from your friendly neighbourhood field trip instructor

Dear geology students everywhere,
Should you be out on a field mapping exercise, and one of the teaching staff does any of the following:
(1) Sits pointedly on or near a particular outcrop as you wander past;
(2) Deliberately wanders off in a different direction to the one you’re taking;
(3) Spends several minutes closely examining a particular part of the outcrop you’re currently working on;
(4) Says, “aren’t you going to look at that outcrop up there?” or, “maybe you should check what’s over the over side of that ridge…”;
or (5) Jumps up and down and shouts, “Look at this!”;
it might be worth your while to take the (increasingly unsubtle) hint.
I’ve just had, an interesting, if tiring, couple of weeks in the Barberton region. Lots of things to talk about in the next few days. First, though, I need to reacquaint myself with proper coffee.
