If you've ever had an alcoholic beverage, you'd know that they have a distinct smell. It's not exactly appropriate in society to give someone an alcoholic drink, unless they ask for one or you're in a bar anyway and feel like being generous.
I've had half a bottle of some sort of mixed "Alcoholic blue cordial" but I've never truly touched the stuff since because of how horrid it stinks,
just from smelling an semi-empty bottle of the stuff (out of curiosity) and your statement is only half true if requested it is then up to your 'rational decision-making' as to whether you allow the asking person (in a bar or not) to have a drink knowing its risks and that your responsible for any outcome that follows afterward.
Not really. In a bar, people love it when you buy them drinks. I do believe this applies to pretty much all of the western world. It would actually be rude to refuse a drink when someone else is buying.
However, at someone's home, it is considered strange or creepy to give a guest an alcoholic beverage, and the chances are that they'll think you're trying to take advantage of them, since ethanol can severely inhibit a person's rational thinking/judgement.
English correction initialize! 1st panel: Twilight: "Colors" is a noun, and must have a particle, but since you're referring to definite colors, (the colors in the picture) you must use "The" "Hey! The colors are back!" Just remember, if you're in America spell it "color" if you are not in America spell it "colour". A subtle difference, but it exists.
2nd panel: Rainbow Dash: Since "Cider" is a liquid, like water, you can't have a singularity of cider. Here you must use a different particle. You could use "some": "Could I have some fresh cider if I ask nicely?", or you could use a quantitative particle. "Could I have a mug of fresh cider if I ask nicely?". You should probably use the first one because it's shorter.
4th panel: Twilight: Nothing big, just "to" is the wrong word to use after recommend if you're recommending to Rainbow Dash. Rainbow Dash is a person, and so would be addressed as "you". So just correct "to" to "you". Also, "Still" is wrong, because she never established a point. It's just not needed. "I don't recommend you drink that!"
