Draco could feel his face blush slightly noting how different he was as he settled down to eat. He saw how Jake noticed and felt bad for making him feel uncomfortable. It was so ingrained into him to eat properly no matter who he was with. Tonks had even made a comment at one point saying to relax and enjoy the meal.

No matter how he tried to blend in something he did or said would stick out. He only hoped that over time it would get easier and he didn't fail.
