Feeling ungrateful. :/

So I really try not to post negative and ungrateful updates but lately I have been really questioning the hand of cards I have been dealt...

I'm currently watching two kids, a brother and sister, and it makes me sad inside to see how well behaved and loving towards each other they are.. I don't know if it's a boy/age thing, or just a Meade thing, but my boys are not at all affectionate with one another. Dylan steals everything Tyler is playing with and in return Tyler is aggresive with him. It's a constant, exhuasting battle. I was a believer that God only gives us what he knows we can handle but lately I'm not too sure... I'm hoping that by posting this I will look back on it in a year or so and remember how I felt and feel even more grateful about my 'cards'..
