Dear Little Sims,
I know a good number of you are vampires. You really don't need to growl in the middle of a pleasant conversation to remind everybody. Also: please, please stop eating human food when you know you shouldn't; subpar vegetable dumplings aren't worth the extreme digestive discomfort *or* the 20-30 in-game minutes spent polishing the porcelain throne afterwards. (I'M LOOKING AT YOU, BEELZEBUB.)
You probably shouldn't praise your dogs immediately after they've been snarling and snapping at each other, either. Just a thought.
