Resentment. We all feel it from time to time.

It’s like the invisible undertow in the ocean that sweeps away even the most experienced swimmer. It pulls at us. It sucks us down into a pit of bitterness.

We hold a grudge. We secretly fume about what he said or she did. We keep a running list of how we’ve been wronged. We review how we’ve been hurt.

It is subtle until it is sudden.
