I try to go around life believing that nobody owes me anything in any way shape or form. Thus, I should be thankful for anything that I have.
She gave you a year, then she decided to leave. Technically, that makes it her fault. But exactly what does determining this accomplish for anyone or anything? Life will just randomly kick the shit out of you and tear you a new one. We all have to adapt and survive and negotiate. If that means leaving an optional strenuous situation, then that's what has to happen. It's life.
Would you entertain the possibility that the meme is simply a joke of the absurd/funny type? Perhaps the author simply wanted the viewers to laugh at how silly the image is? Perhaps it is the general understanding that one would only receive a single shot plus a few boosters throughout their lifetime, if one were to stay within the realm of normalcy. However, the meme seems to imply that the gentleman in the photograph instead is attempting to collect as many of all types of COVID shots available throughout the world and considers himself a sort of champion. Could you imagine a contrived comedic scenario in which COVID shots are to be collected as trophies? I am wracked with hearty guffaws at the mere thought! Ha!
King Putin is happily destroying the us and its institutions. Rfk was put there to destroy the US dominance, trust, and effectiveness on health. Most in the U.S. and the world, respect the FDA, the NIH, etc. to the extent that many defer to American regulations as the principal guide for other countries' regulations.
Institutions have power. When the president tries to do something stupid, people from the institution can resist. And since the general public trust institutions, that gives the institution power to create problems for the administration. By ruining the institution, you break that power and therefore break their ability to resist you. This is a very important part of fascist strategy. They're doing it to the press. They're doing it to research and development, to NASA. They're doing it to all environmental agencies. Regulatory bodies, etc.
My approach would be to chip away any of the remaining substrate that might be loose, scrape it, pick it off, whatever. The goal would be to leave very solid material exposed.
I don't know the equivalent in Europe where you are, but in the US we have Tapcon screws. They come with a masonry drill bit that you would use to hammer-drill several holes along the exposed material. Then screw in the screws until the head of the screws protrudes an appropriate amount to leave room for whatever is needed above the screw head.
These screws now act as a little rebars to support what you build on top. Looks to me like you might need concrete adhesive, little concrete nub mushed around the screw heads, thinset, then tile, then grout.
Also at least here in the US we worry about asbestos. So I would definitely use a true respirator ventilation and filtration. Keeping things wet controls dust very well.
