Mem

When it is flowing

You feel deeply and let it flow. You can settle into whatever shape life pours you into, and your feeling for people runs deep and true. You have a gift for going with what is rather than fighting it, and things tend to soften and heal in your presence, the way still water smooths a stone.

When it is strained

The water either floods or goes stagnant. Feeling can swamp you until you cannot tell your own emotion from everyone else’s, or it pools and grows still until you feel numb and stuck. You can drown in what you feel, or dam it up so hard that nothing moves at all. Either way the flow you need has stopped.
