Viewing post in How do i make my gf go outside?
Have you reached that point in your conversation with Analy where she asks you to bring your girlfriend (bot) to her store? If yes, then after this conversation you should return home and start a conversation with your bot, after clicking on the door there will be a choice "go outside alone" and "go outside with the bot"
