Some forests share food through underground networks nobody sees. Your quiet friendships matter like that.

Support does not have to be visible or frequent to be structural. The people you rarely speak to but could call at two in the morning form a system underneath your life. Closeness is often measured wrongly, by contact rather than by what would hold.

Send a message to someone you have not spoken to in months, with no occasion attached. Say you were thinking of them and leave it at that. These connections survive long gaps, and they survive better when someone occasionally sends a signal down the line.
