One or more characters I drew actually scare me. This is a first.

The cytoplasm surrounds the nucleus of cells.

no laughing matter

This isn't school, but I couldn't resist. When my team tweeted that Rich Ohrnberger had visited Brigham Women's Hospital, I thought "aw!" Now I'm just worried about him and wondering if I should try and contact his manager to make sure he's still alive.
