A Bit of a Rant

I wouldn't mind so much if I got a word of thanks. 

 I wouldn't mind going out at 9 pm, 2 hours after I'm usually  in my goonie, to pick her up from some place she's been.

I wouldn't mind driving all over hell's half-acre to get  the things she needs for her trip to Italy & Greece for March Break.

I wouldn't mind going out to the business supply store to buy the required display thingy for the science fair project.

I wouldn't mind driving her back and forth to the science fair partner's house to work on said science fair project.

I wouldn't mind doing an extra load of wash because she forgot to give me her gym uniform on wash day and needs it for tomorrow.

I wouldn't mind buying the soy milk she asked for because she "wants to try it" even though I know she'll take one sip and declared it disgusting and then I will have to throw it out (she's been told she will have to pay for it).

I wouldn't mind any of these things if I got one word, even a mumble of thanks.  But I don't and I'm feeling a bit put out by it.  Lately, I feel like I'm the scivvy who's here to wait on her hand and foot.  This lack of gratitude is making me resentful and that's a feeling I don't really like. 

Is it her age?  She's thirteen and by all accounts, teen-agers are the most ego-centric, self-centred narcissistic creatures that walk the planet.  Does that excuse the behaviour?  I don't think so.  It's just common courtesy really.  If another adult were to do these things, thanks would be offered. 

Is it me?  Am I a push-over?  Is there some vibe I give out that shouts take advantage? 

Whatever it is,  I'm getting pissed off.
