I now realise that by using 'I thought' when writing in first person past tense, you are not making your character strong enough. What is best 1 or 2?
1. I thought Ruby deserved better treatment after last night.
2. Ruby deserved better treatment after last night.
So, it's a case of not having the 'I thought' , break in the sentence. It kind of makes the character weaker, almost as if she's not sure in Example 1.
Just a tip, that's all, when editing. Get closer to your character and make him or her stronger. Allow them to make more positive statements and decisions.
I've modified this post because I realised there are a few more redundant phrases you might consider deleting. They are: I wondered, I pondered, and I questioned.
