Storm Moodlet Tweak  

With this mod, not all sims will get a stressed/sad moodlet while inside during a thunderstorm. For instance, most children and toddlers will fear thunderstorms, but wild toddlers or loud children (childhood phase) won't. On the contrary, only few adults will fear thunderstorms - there are exeptions for e. g. squeamisch sims, Sims who hate rain or wind, though.
