A Thief?

The Hospital food that delivered to Tami is hardly edible.  So i try to supplement that by bringing food and healthy snack down to Tami so her breast milk will be healthy for Ashlynn.  On Tuesday i dropped off 4 frozen dinners, Tami marked them then put them back into the plastic QFC bag, tied it, then placed it in the community freezer shared with other people in our section.  An hour later Tami went back to cook the lasagna and it was gone. In its place was some sort of chicken pot pie.  Is that a thief or a prank?  That person knew it did not belong to them,  they even opened the QFC bag to get it.  I am going to get another one and inject it with exlax. Just kidding.  If it was one of the teenagers then I will go get more for them,  just save us some.
