sweet hearts

so, my engaged friends and i were sharing a package of sweet hearts last night. we were eating them in no particular order (meaning we didn't take turns eating them), yet on every single one i got, the message was a single persons message (ie 'shy girl' or 'funny face' or 'smiles') and everyone they got was a gushy, couples only message (ie 'sugar lips' or 'your mine' or 'my girl'. how is that possible? do the sweet hearts know who's going to eat them and speak specifically to them? i'm thinking they do. my personal favorite message for me was 'hard luck'. oh sweet hearts, don't you know it.
