Lavender Brown and Horace Slughorn
Although the ancient house of Brown wasn't all that noble, it was still an ancient pureblooded house of wizards. Her father and mother were quite traditional, although not to the point of being death eaters or hating muggleborns. They simply wanted their daughter to go on and marry a pureblooded man to carry on the family line, then Lavender would get a respectable job and have a few children. Never would they question if this was actually what Lavender wanted. It was a shock for her parents when she was sorted into not Ravenclaw or Slytherin but Gryffindor, but it would have been worse if it was Hufflepuff, so it wasn't too bad. Lavender was so glad that she hadn't been sorted into Slytherin, even if it did cause her parents to be shunned by their social circle. Slytherin had never been what she wanted, she wasn't evil, she wasn't ambitious and she wasn't cunning. No way would she have fitted in. Professor Horace Slughorn was the embodiment of Slytherin, he made her blood boil with his name dropping; he was so see through, you could obviously tell that he was only after people for their connections. He had ambition, that was for certain. Lavender couldn't stand to be any more Slytherin or near Slytherins than she had to. That's why she turned down Colin Creevey's invitation to Slughorn's party and ruined the start of what could have been a very good relationship…
