Sir Gawain and the Green Knight - Part 1 & 2

I really like parts 1 & 2 of Sir Gawain and the Green Knight. Well, except those 4 lines that comes in every paragraph. I was sooo confused. Anyways, this poem goes back when the Greeks destroyed Troy. In Part 1, it was New Years; there were a lot of festivities going on. People having fun, laughing, and having the time of their lives. There were even those that were just drunks. This also goes back in the Renaissance Period. So the Green Knight, who rode on horse, strolled in like he was the best there was, asked for the captain out of the group. He wanted someone to hit him with his axe. The exchange would be that someone would strike him back. As soon as he asked that, there was nothing but silence. There were probably even crickets chirping. The one thing I didn't quite catch was lines 246-249. I think it meant that some were scared to even say a word and let the person who's courageous even to speak out. Instead, King Arthur had some dignity and talked to him himself. I was shocked when the Green Knight called out the knights for a challenge. I just wanted to know why none of them had the guts to face him. It's not like he wanted to kill them or anything. Is it because they didn't want to get embarrassed, or they didn't want to lose their reputation as a knight? If so, a knight should've had the courage to stand up and face a challenge, but it's not like they had a choice in the matter. So they're sitting on the benches with their strengths nothing compared to the Green Knight. Here's the thing: here in the 21st century, when we get called out for a fight or "challenge," we can either accept it or leave and call it a day. Back then, it wasn't like that. Whoever was called out, have to accept it no matter the circumstances. Now here's what's terrifying me: Sir Gawain cut the Green Knight's head off and I guess he thought that he knew he was going to die just like that. I was fooled that he was going to die in an instant. The knight picked his own head off and told Gawain to meet him at the Green Chapel so that he came receive the same blow that he gave the Green Knight. In Part 2, Sir Gawain was all armored and shielded up and even wore a pentangle (a five - pointed star). I felt that just because he wore that, he feels that he accomplished something. So while on his trip, he found himself at some sort of castle where he was greeted by a host. Lord Bertilak & his wife were there as well. But there were some exchanges involved between them and he accepted it. But didn't Gawain accept a previous request? I liked where the wife tried to seduce Gawain and he kind of backed away, well except for the three kisses. But he did keep the girdle. I guess he needed it against the Green Knight or something like that. When he left to find him, he saw him fixing his axe like he was ready to fight. But Gawain, clueless as ever, bends over to get the blow that was agreed upon, but turns out he found out that it was a game the whole entire time. At that point, he was feeling shame and had to wear the girdle. I would've felt shame too if I would've been in his position.
