cool ways to stop theft

hi, my sister keeps on coming into my room, taking things and being mean about it, if anyone else is suffering through this as well i've made a list

1. in a safe

2. in a fridge (prevention of entry not 100% guaranteed)

3. in a red pen (no one wants to steal a red pen lol!)

4. in a vent

5. swallow it and keep it in your stomach

6. keep it in your many assorted bodily holes to choose from

7. in a pillowcase

8. in a locked room

9. a fat pile of dirty socks

10. in a shampoo bottle

instead of hiding it, here's some ways to avoid being put in the situation

1. don't own anything

2. but everything in the most steal-proof safe

3. own everything ever created so they have nothing but their bare hands to steal

4. have disgusting things no one wants

5. have an alarm system and show it on signs on your lawn

6. travel forwards in time to where the sun swallowed the earth and be the only person that exists
