Connecting Idea

What is connecting? Plugs and outlets seem appropriate, as they are meant to connect. I would use electricity as a way to make the power of connection clear. Chains, puzzles, and keys also fit the idea of things that are meant to connect. But connecting can also be in terms of relationships such as friendships, symbolized by playgrounds and phones, or family, symbolized by dinner tables and food. Hand holding is also an organic type of connection, while plugs and outlets might be less organic, but easier to read. I would like my main idea to be a combination of plugs and another organic idea, such as holding hands.
