The only way to have a friend is to be one.

Friendship is not something you find already made and step into. It gets built by someone going first: remembering the thing, making the call, being there when it is inconvenient. Waiting to be chosen feels safer, but it leaves you with a life of acquaintances who were also waiting.

Think of one person you would like to be closer to, and do the small unrequested thing this week. Send the message without needing a reason. Do it a second time before you judge whether it worked, since most friendships are slow before they are anything.
