Bitter Ending

I should be happy with today. Instead of going out to eat with a couple of friends, I decided to play in a few 180 man $4.40 sit n gos. I finished 2nd in one of them with no other cashes. It's pretty disheartening when a complete donkey beats you. The final hand was just ridiculous. The blinds were 1500/3000 with a 300 ante. I had about 110,000 and he had about 160,000. He was on the button and min raised to 6000. I had 88, so I popped it up to 27,000. He flat called me. The flop was 7 8 10 with 2 spades. I check, and he bet 21,000. I shoved the rest of my stack and he insta calls with 56 offsuit. The 4 fell on the river, and good game me. He told me I should have shoved pre if I wanted him to fold. So needless to say, I was bitter. Oh well, I'm sure I'll be at plenty more final tables.
