Schooling Mom ~~ Is this bullying?

Well, we're on week 3 of school around our house.  Things are going better than expected.  Ren is getting along really well at school and making lots of new friends.  All of which are girls.  He's constantly telling us about this pretty little girl, or that pretty girl.  I think I *may* have a ladies man on my hands.  Help me now...lol!

A though, is still struggling.  She came home the other day and complained she was bored.  I ask her why she felt that way and she said "because I already know all the stuff we keep doing Mommy".  Uh oh.  Not a good way to begin your school career.  Thinking it is boring.  I do know that starting this week, things are going to change a little.  She is going to start some new things, so hopefully this "boring" phase will end.

The real reason for the title though, is she has been coming home complaining about a little boy.  According to her, "he's mean".  He throws away her things, literally.  He grabbed her hand and took off her silly band ring and threw it away.  What?!?  She also said he's pushed her down in the hallway, throws her art work (that is in her cubby at school) in the garbage and says naughty things to her.  I ask her if she was mean to him and she said "no Mommy.  I'm nice to everyone because that's how to be a friend".  Thankfully that lesson has sunk in!  I have ask if she has said anything to her teacher and she said "yes".  I then ask if he ever gets put into the time out area for doing these things and she said "sometimes". 

My question to you wise parents, is this bullying?  Do I say something to her teacher as well?  Could there be more to the story than this that she isn't telling me about?  A is a very helpful, bright girl and in the past week she's been moody (although I think she's still adjusting to school in general), and just not her chatty, happy self.  Can this really start in Kindergarten?  Am I reading into this too much?  Advice please and thank you!
