Locking your doors

We are having a discussion on one of my birth boards from my older kids about locking doors and security alarms. There are many of us (me included) who do not lock our doors at home (I actually don't even have a deadbolt on my house and we don't lock it when we leave either), and others who think that's totally weird. So what do you do? Do you lock your doors? Do you think it's weird that people don't?

My landlord is pissing my tf off. I burnt a tortilla and I open my front door and screen door she comes up to the door and goes um is there a reason the doors up like wtf. I pay my rent can I not have my fucking door open

I run to the door when I hear the elote man!
