[L&D] Thanatology Skill

Can the Thanatology Skill be overhauled in the next update so sims who maxed the skill will only 'Speak A Dead Language' to sims who either also have the skill maxed or are Macabre? Because every 5 minutes(real time) one of my sims, who maxed the skill, constantly does the 'Speak A Dead Language' interaction on his own and it's starting to bother me. None of his family members has the skill and they give him odd looks.
