The conversation from a fortnight ago with Tonks did not cross his mind much at all. She had the right to feel however she wanted, and Charlie did not have cruel intentions or mean to offend her (which he assumed Tonks would have known). Pregnant women, at least from Charlie's experiences, were highly emotional and often irrational—perhaps that was Tonks, perhaps he was wrong, but either way Charlie let it roll off his back like water off a duck. He did not want to risk his friendship with Tonks (and maybe he did say the wrong things, albeit unintentionally).
"Good evening," he said, getting to the front door not too long after Tonks. Stepping up beside her, he grinned, "the flowers are beautiful," he said, leaning in to kiss Tonks on the cheek in greeting. "It's good to see you again, and this time away from school."
Charlie's house-warming gift to Bill and Fleur was an old set of candlesticks that belonged to their great-great-grandmother—or so he was told. They were neatly wrapped (or as neat as Charlie could get it). He was very much looking forward to seeing his brother and sister-in-law. "I like what they've done with the outside," he said, looking around a bit. "I bet it'll look just like the Burrow one day," he said with a bit of a laugh.
