Venting my Frustration

My apologies to anyone who might actually read this.  I am frustrated.  I must vent.  And I refuse to burden anyone in my real life with such petty bullshit. 
I work at an insurance company.
A member of my team at work had a question on a policy regarding the rating and discounts on a vehicle. 
I knew the answer to the question.  I have a VA state P&C license - which shows I'm legally allowed to answer such questions to the public. 
But in other respects, it also shows that I know WTF I'm saying. 
Our trainer sits in the cubicle on the other side of the wall from me. 
So while I'm asking supplemental questions to the teammate and subsequently giving the correct answer, the trainer is going through online manual after online manual and instant messaging cohorts in order to find the answer.  It took her 12 minutes to find the exact answer I was able to give immediately. 

SUMUP:
The trainer didn't know the answer to the fracking question. 
I knew the answer off the top of my head. 
Isn't this the type of thing a trainer ought to know?

And yet here I am... still in my lower function. 
Unable to give answers even though I know what I'm saying.
Still making lowly money. Still with lowly status.

Meanwhile, our trainer  (a person who I had to correct on multiple occasions during our training class a few months ago and clearly doesn't know the answers to even the simplest questions) is sitting 2 tiers above me making much more money than I am and just that much higher up the career ladder.

W. T. F. ???????

*sigh*
I need to breathe and relax.
I've only been back in this company for 7 months.
(side note: I worked here previously for 5 1/2 years and left to be a SAHM, then to pursue other avenues... after just over 3 years - I'm back)  
I have not yet "technically" even reached my 1 year anniversary.  Having been gone for longer than 12 months, I have completely lost my previous tenure.  So I must start from scratch all over again. 
Its frustrating. 
Its maddening. 
But it is what it is. 
I must bide my time. 
I must keep my head down. 
I must keep my mouth shut. 
I must do my work. 
I must do my work properly. 
I must do my work well. 
I must show what I know and keep records of all the times I've had to correct the trainer. 
I will be successful.

Today's Outfit: jeans and a button down black shirt with 3/4 length sleeves.  Nothing fancy.  Nothing notable.  But very very comfy :)
Today's mood: Overall, very positive.  I got my annual merit increase.  My oldest jiblet won her classroom spelling bee.  And its date night after work!!
