"For every action, there is an equal and opposite reaction"...

The things we have done, good or bad, all have a way of coming back at us. There are always reactions to EVERY action. You may not even realize that is why something is happening, or it may not happen soon after your action. You may think that you got by unscathed, but you didn't. There will be a reaction sooner or later. You have to be careful. Karma is only a b*tch if you are. That isn't to say nothing bad will happen to you if you don't do anything bad. That is definitely not the case. Sometimes, bad things happen to prove to you that you are strong enough to handle whatever may come your way, and sometimes, bad things happen for unknown reasons. Sometimes, things happen because they just do.
