I had a similar problem - and no real solution.
I looked at several calculators. Some want to know the size of the windows, location of the windows (direct sunlight), etc. That obviously makes sense. But I didn't see any AC calculator which asks about the desired room temperature.
I.e. do you want in the living room 26 degrees Celsius? Or 24? Or cooler? Obviously the AC has to work harder if someone wants 22 degrees inside temperature while the sun is shining in the windows in the afternoon.
So I think one question you have to ask yourself is how cold should it be. If you have visitors from Siberia in your guest house who think 22 degrees is warm then better buy a bigger AC.
Or maybe you don't need a big AC if the family from Thailand stays there and is happy with 26-degree room temperature.
First I would run the Windows update, that maybe will fix these issues.
Next, Windows troubleshooter.
If you are not sure, publish a list of the programs which you have installed. You can make a screenshot.
Listen to Bjørn Lomborg and others who look at reality and don't panic.
Sorry, it is a 4-hour interview. Some things are too difficult to explain in a TikTok video.
Some time ago a friend gave me a book about many of those phrases. It was divided into section like nautical terms, etc.
We use so many of them all the time and most of the time we have no clue where they come from.
That reminds me of my War of Terror T-shirt with George W Bush.
My Thai gf was wearing it once at the time when the USA invaded Iraq. She received lot of bad looks from all those holy Americans...
You don't get the part that they just don't care. They drive where they want and don't give a f#$# about anybody else.
Obviously that is no reason to shoot her. But hopefully she will remember this for her next time on the road.
Out of interest, why would you wear it?
Most people won't recognize it.
Maybe Russian will recognize it and some will agree and some wont. Do you want to discuss this with them? Or do you want that they feel bad about their leader?
And maybe people from Ukraine will recognize it. Do you think they will say: Finally someone supports us, everybody else likes Russia? Or what?
What's the point?
