That he drinks carefully and with grace. Trying not to disturb it too much. (but why a tasty drink?)
He loves Pepsi like he would love a friend.
It means drinks redwine with... It can mean, I drink redwine with cheese, or it can mean he drinks redwine with a friend...
He means he drinks a lot of it
You mean drinks in general? Alcohol fizzy drinks like coke fanta etc?
they like you as a friend
It depends what way you mean. If you mean like as in fancy then theres nothing wrong with that. If you mean like as in friendship like then obviously otherwise they aren't your best friend.
A friend calling you bossy and laughing weird can indicate that they are getting annoyed with you, but this does not mean that they do not like you.
When a friend likes you for what you are, it is called genuine and authentic.
it mean he likes you more than a friend or he hates you
A guy said, "I like you," then quickly added, "only as a friend though," what does that mean?
Do you mean stuff like Coke and Pepsi? If so, these drinks are highly acidic and worsen ulcers.
That you're not my friend
