The mystery of the missing Garlic Skyflakes

Last week, I bought this pack of garlic skyflakes - a 10-pc pack-of-threes. I’m trying to watch what I’m eating lately so I’ve counted a grand total of 3 packs consumed last week - at the most. Today, when I came back to the dorm, there are only 4 packs left in my food bin. My friend from this floor - the only person who gets food from me - said she didn’t take any. So the question begs to be asked - who took my motherfucking skyflakes?

I’m not sure how much I’ve eaten exactly (might be two or three), but I’m pretty sure it was not six. Yup, I’m sure it wasn’t six. 

edit: my wastebin of two weeks says I’ve only eaten two, so…
