Base building in a world of zombies

Auto cards enabled. You were always a bit of a prepper, and covid didn't help your stocking habits. When the zombie outbreak happens, you see a survivor through your security cameras. What will you do? Will you take them in? Ignore them? Your have a moderate sized two story house with a basement, including a 3 bedrooms, 1 bathroom, kitchen, garage, laundry room, living and family rooms, plus a small room used for your hobbies. The basement and kitchen are fully stocked, a rifle with 1200 bullets, a gift from your dad, sit in a safe. You'll be fine on your own, for a while. Another person means risk, but it also means you'll have someone to talk to, someone to rely on. You can help that person, or wait, and find someone else. You can't save everyone, heck, you might not even be able to save yourself. Who knows, maybe if you feel like it, you could even try and make your own group?
