Packing lunch for school

So I wrote previously that I pack lunch for Terran and I try to keep it as American as possible. This is true. I do try. But these days, even though I try, it's starting to look more like a Japanese obento box. Firstly, I do use a bento box that my mom got in Japan. The size is perfect for a kid's lunch. Secondly, Terran asked me to make onigiri. I use to pack crackers for carbs but he stopped eating them. So I packed onigiri and this made it really Japanese. I am guessing that maybe it's OK for a kindergartner.

One good thing is that he told me that he wanted to buy lunch at school sometimes. So I let him buy it today and he liked it. This makes it so easy for me (all I need to do is give him $2.50) but I don't like it that I have no idea what he eats and how much. For example, he told me today that he got a hot dog, apple pie, blueberries, and milk. He told me that he ate them all (yeah right). But I didn't see hot dogs or apple pie on the lunch menu so I don't know what he's talking about. Also, when he came back, he was starving and he ate a bowl of ice cream, one bagel bite, and 2 bowls of noodles. So I am just not convinced that he ate anything at all. When I pack lunch, I can see what he ate by what he brings home that's left over. Couple of days ago, I noticed that all he ate were fruits. I got mad and asked why and he told me that they only give him a few minutes to eat. This is also not true as I know that they get 30 minutes for lunch. He was probably too busy chatting with friends and stuff. I just don't know how he gets through the afternoon on an empty stomach. Agh, I wish he'd shut up and eat.

Does this look too Japanese?
