and now you have these tendencies to be occasionally inclined toward bullying. But now that you recognize them you can resist them and when you fail, attempt to make amends. Work on it and over time you have to resist less and less because your tendencies will change.

In other words, if you work towards making yourself a better person, it will just become habitual.

As for sneezing... I think you're just taking it all too personally. The person is probably just accustomed to saying bless you in those situations, and being offended is less a matter of being offended by religion being "pushed" on you, and more a matter of just being offended by the fact that they themselves are religious.

Do you realise that atheists and agnostics have nothing to say after someone sneezes? Just stare at them blankly till they excuse themselves...
