<human>: I'm not sure if this is the right place to post this but I am at loss of what to do.

I have been living with this girl named e for a year now and none of my stuff has been misplaced until a new housemate comes in, named s.

A few nights ago I noticed my hot dogs went missing as well as some of my apple juice and my sipahhh straw. 

I found the empty hot dog packet in the big bin and when I came home last night I noticed an empty sipahhh rapper next to a carton of milk on the bench. And e doesn't buy cartons of milk only s does.

I confronted both e and s and they both denied ever eating or taking any of my food. It just doesn't make sense.

Then e tells me that her vanilla yogurt gas gone missing. And I already have my own yoghurt and I promised that I didn't take it so of course it must be s. 

S tells me she doesn't even know what a hot dog looks like and she's never lied in her whole life because she wasn't brought up that way. We had a screaming match where she tells me she is also allergic to something in vanilla so she didn't take the yoghurt and when I confronted her about the apple juice she said she has her own food and has only eaten her own food since she moved in.

I then noticed she has bought her own apple juice and I am starting to connect the dots. 

I don't know if any of my belongings are safe anymore. Casper couldn't have taken them and I trust e more than s. 

Reddit, what should I do?
