Almost every English grammar book I`ve studied claims that "Will" is used to talk about plans decided at the moment of speaking. Sentences like "I will help you" or "I'll wait for you" give a strong impression of spontaneity. My question is the following:
When modified with "Maybe" or "I think" , does "Will" convey the same meaning? Or perhaps it shifts the meaning into something that's more concidered and deliberate? Let me give you a few examples:
"I think I'll watch a movie this evening"
"Maybe I'll read a book"
Do those sentences sound like a plan made before or at the moment of speaking?
