If you want those messages to stop, you may be interested in "enemiesaccumulate.package" from the Director's Cut package, which makes a few sanity changes to relational decay and enemy accumulation (such as allowing your grouchy sims to maintain their enemies without suddenly forgetting that they hate them, and if the little wussy isn't enough of a bastard to return the favor, make sure he does with some PHONE HARASSMENT!). It also moves relational decay to the start of the day, rather than midway through, makes friendship decay probabilistic in best friends (you have a 10/X chance of any best-friend relationship decaying every day, where X is the number of your best friends). Because let's face it, watching your sims spend 5 hours on the phone, during which you cannot save the game at all, gets old, uninteresting and tiresome fast, and I figure that 10 is a reasonable number which keeps the actual difficulty while dropping the tedium.
