OK, here's one:
How about letting more than one villager acquire skill points from an event?
Specifically, when two villagers go off to the honeymoon hut, shouldn't BOTH of them get Breeding boosts?

This would also allow the "Teaching" event to be something useful. For instance, when a Master builder, farmer, or researcher is working with another villager of a lower level, the lesser experienced villager gets a skill boost. (Possibly with a decreased productivity for the master, or transferring the boost that the master would have received to a co-worker.)

While we're at it, shouldn't the nursing mothers get a parenting/breeding skill boost for all the time that they spend caring for the little spuds?
