Must look more closely.

It never fails to amaze me, the wobbliness of the English language.
Who but the English would erect a sign, beyond the item to warn one of an impending item?
Can't beat a REALLY GOOD stir.
That's up alongside one I saw and one I heard recently.
Taking the heard one first:- You know the
"Press A for thingy": "Press B for Wotnot": "Press C for thingumybob"?
I listened, carefully, to a list of that type and at the end I was invited -
IN ENGLISH to press button "X" if I'd like to hear it in Welsh?
DUH?!?!?!? Why wasn't I invited in Welsh?
The second one I wouldn't have seen but for the actions of my warped, twisted, EVIL, malicious, S in Law, who has persuaded She who must be obeyed to give consideration to the concept of "Decluttering".
A document passed through my hands inviting me to do whatever-it-was to get the form in Welsh Lookyou. BUT it told me, to do so - in ENGLISH.
:¬((
Anyway, back to the Blip - MUST remember to check and see what there is on the other side of the "monolith".
The "Extra" would have been the Main, but for the fact that it was spotted on the way in and there was nowhere convenient to stop & get the shot including the message on the way out.
