the older brother

i live on a farm with my dad and younger brother. last summer my brother turned 18, and decided to go on an adventure. now, my father doesn't have a lot of money. in fact, we're barely making it. but my dad was going to split his money between me and my brother when he died. but on my brothers birthday, he asked for his share of the money for his adventure. my dad never could say no to him, so half our money went with him.
he went to Vegas, and spent all the money on gambling and whores. he ended up having to get a job delivering pizza, and spent everything he earned on his bills. i'm not sure what happened after that, i'm assuming he got tired of being an "adult", but one day he just showed up back home. my dad insisted on buying him new clothes and threw him a huge party.
while my brother had been spending his money, i'd been doing his work plus my own on the farm. i tried to do as much as possible for my dad, so i never asked for new clothes or anything, and i definitely never asked if i could have a party. i mean, theres no way we had the money for it. we were barely paying the bills. but now that my brother is back from his little adventure, tired of being an adult, having spent half my dads money, and WASTED it, my dad just give him a party!! and does he even let me know? of course not.
i came back from a long day in the field, and all i hear is music coming from the house. there are tons of cars parked outside, and people everywhere talking and laughing. i went up to one of my friends and asked what was going on. he looked at me like i was crazy and yelled over the music " your brothers back, we're having a party!" i didn't know what he was talking about, i though my brother was still in Vegas or wherever. but i looked around, and sure enough, there was my brother, talking and laughing with people. i was pissed. i wanted to kill him!
but i went to my dad instead. he asked why i looked so upset. i explained, and i figured since he was a fairly reasonable man he would realize he should punish my brother for wasting all his money instead of giving him a welcome home party. but instead, this is what he said: "my son, you are always with me, and everything i have is yours. but we had to celebrate and be glad, because this brother of yours was dead and is alive, he was lost and is found."
that confused me for a while, but then i realized what he was trying to say. because i stayed with him instead of going off on my own, i would receive everything in the end. but my brother had run off and lost everything, and when he left it was like he had died. by returning, and my father accepting him back into our family, he was coming back to life. he father completely erased the memories of any wrong he had done, and gave him a fresh start.
