All of us wear masks from time to time, unless a person has a brain disability and loses /never learns their inhibitions. Young children also tend to be uncontrived until they learn to lie.
Occasionally, though, you come across someone to whom the mask is essential, a hiding place for them, and a bait for you. It doesn't come off in private until you're in so deep you're invested already. Then they start to fillet you.
When you do get thrown back, and start to swim away, they put the mask back on and reel you in once more, to do it all over again, and again.
They've been doing it for so long, almost their whole life, they're exquisitely beautiful at it. Quite fascinating to watch, infinitely pleasurable to experience. You make that suicide leap into the boat and submit to be gutted. That's when you realise, abruptly, that the pleasure's not going to be infinite, though the cycle may well be.
It's now a modern world of dating apps, where filters seem to be accepted for profile photos (I don't see the point, seems a bit like stuffing padding in your underwear, surely you're going to be found out if things go well?) People can misrepresent themselves in all kinds of ways, though, appearance being the least problematic.
So how does one figure out if the prospect has a mask on? Are they Jekyll and Hyde? Well I think the old adage goes "if it seems too good to be true it probably is."
