yes, I don't feel too safe, plus I feel my privacy is being violated when some kid is in the house or walking around outside. It seems a little weird teenagers would want to be spending their summer days around this house anyway.
I already did call the cops a few days ago about my dad taking stuff that was specifically mine and the cop told him to not take my stuff and to ask before selling things. The cop did say it was theft when he takes my things.
While my mom is an adult, she's on disability and has beginning signs of dementia (which might be for another forum), but it's hard to convince her to start preparing or talking to her on what we can do.
