Modals of deduction (past) 1 Its a real antique. I bet he paid a lots for that. 2: I'm not sure if I paid or not . I can't remember.
3: She's not talking to me. Maybe I said something to upset her.
4 You live next door to the crime scene. I'm sure you heard something.

what is the question.. you are more likely giving us something to read with no question

yes, it can be both.

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !
