I am often complimented on my amazing memory for facts and figures about obscure places and things.
Actually, I don’t retain any of that knowledge between trips unless it is a place I visit often. I have printed out notes about the places that I read out. You can’t see me do it and I paraphrase enough that it comes across as me simply talking about what I know. If there’s internet access, then 10km before town sees me hitting the google. You could actually do that yourself.
If I can’t remember a time date, then I’ll fudge the issue. Use a lot of phrases like “I believe it might have been around —-“. “Hearsay has it….”.
I will never outright lie to you but it is shaky ground. To make myself feel better about it, I think of it as tour summation, ala TL;DR.
I tell you personal things about places I’ve been to.
This may happen because a) I’ve forgotten facts/have no internet and want to distract you from my lack of knowledge, or b) I think that telling you stories about my life will make you see me as a person and that helps immeasurably when it comes to tour issues.
You might rant and rave about whatever it is but in writing your letter of complaint to the office, you will always speak favourably about me.
