I have a question about English.

In favor is a prepositional phrase, I is the subject, am is the predicate, sure = surely = absolutely, the adverb modifies in favor

in favor of your decision is the entire predicate

The sentence can be seen as I am in favor of your decision. The main system is obvious

told does not use the past perfect tense because there is no corresponding explanation in the context, so there is no need to use the past perfect tense.

For example,

"Do you know what people called you recently?"

"Yea, Tom has told me about it."

To pick here is the infinitive as an adverbial of purpose. Since it is an infinitive, pick must have a prototype.

As for what you said about "told having an impact on pick", an action starts from a certain moment in the past and continues until another action occurs. This can constitute the impact you are talking about. In the original sentence, it becomes told that it has been happening until daddy picked it up. This is obviously illogical. The relationship between these two actions is just that they happened one after another in the past tense.

That is, After I told daddy that I wanted blue, he picked blue ones for me.
