For Aslan pls. Why were people described as neighbourly and cheerful this season?

The crops were unusually free of deviations that season. This meant that farmers did not have to destroy their harvests. This put people in a better mood. Old Jacob, who is usually pessimistic, admitted, “Merciful, the Lord is”, he said…..He then goes on to say something is bound to go wrong but I guess that was pretty optimistic for him!
