perhaps you have moved from a place where it was easy to see the negatives into a place where you are filling it with positives
each situation could be taken in different ways
a resentful (not that you were...just using it as an example) could have seen the inlaws confession of how difficult it was as them trying to make themselves feel better after abandoning you
coming from a different place, the inviation to sit by them might have been seen as rubbing your face in the fact that you aren't a part of the family anymore
a different person may have seen the letter from the x as snarky like you did all the work and didn't let him be a part of it
when we are looking for blessings they can be found in abundance when we are searching for slights, they surround us
