"You probably shouldn't believe me," he said, breaking into a grin as he added copious amounts of cream and sugar in hopes the coffee would be more drinkable. It almost tasted all right afterward. "And yes, invite her to lunch one weekend so I can meet her. Hogsmeade is coming up soon, isn't it?" Charlie did not keep track of the Hogsmeade schedule too much as he typically popped off during the weekends as long as McGonagall had her back turned (and he would only be gone for a few hours, anything longer he did, in fact, talk to her about).
Raising an eyebrow, Charlie paused as he brought the cup to his lips. "Ginny, I rarely drink," he said seriously. Of all the Weasleys, Charlie was far more serious than others would have expected. It was not that he never drank a beer, he was just very hesitant, nor did he go out and drink for the sake of getting drunk. Charlie chose not to distort his preferred image of being responsible in all aspects of his life. Though he loosened up around his family, he refused to show that side while on-duty, so to speak, for the Order and on Hogwarts' grounds.
"But," he said, looking into the cup, "anything would make this taste better. Even something out of Fred and George's shop. Try this, it's horrible," he said, sliding his coffee to Ginny. "But I can't seem to stop drinking it." Charlie had a caffeine addiction, and he certainly knew it. Pouring himself tea instead, he grabbed another biscuit. "And I won't actually embarrass you. I'll treat you and Sam to lunch in Hogsmeade, though, if you'll let me."
