I think my mom and son broke into my place.
Why do you think they broke in?
I found my old photos planted on my shelf
It was wrong of your mom and son to break into your house, even if they are your family. It's disrespectful to assume that just because you're family that you're allowed to go into someone's home whenever you want.
I couldn't tell that they broke in right away. My mom was smart enough to bypass my security system.
That was wrong of her, she shouldn't have assumed that she could come in even if she is your mother. You should change your alarm system and talk to her.
