Mystery of the day

Xander came home Friday very confused as to why we had put seaweed in his lunch.  "Seaweed?!" Jonathan asked.  Of course we didn't put seaweed in your lunch, he explained.  But Xander was adamant that he had, and that he didn't like it, and didn't want to eat it.  Jonathan was baffled.  But lo and behold, when we opened up his lunchbox, what did we find?  Seaweed.

Our best guess is that it had been packed in the lunchbox of one of his friends, and that friend didn't want to eat it, but didn't want to take it home again.  So it got snuck into Xander's lunchbox when he wasn't looking.  All of us were highly amused.  

And no, we reassured our son, we weren't mad at him, and he didn't have to eat it if he didn't want to. :)
