Can I say "weight" instead of "mass" in this context? Or are they different words?

Native speaker’s answer

Rebecca

In this context, "mass" does mean weight! However, in different contexts, it could mean an object or something with no definite shape. Or a large number of people or objects. Ex: The mass of the object was too big to use for the experiment. Ex: The doctors found an unrecognisable mass in my body. The medical scan shows it. Ex: Masses of people gathered to watch the Christmas lights turn on!

Why does he say "when you're 7 years old" while he's talking about his story? I thought he should say "I'm."
Great question! He uses "you're" to imply that all 7-year-olds do similar things, as though he is addressing everybody who is listening, saying they would have also done the same thing when they were 7. It means the same thing as saying "I did the only thing available any 7 years old would do".

What does "get lost" mean? I thought it means to not know where to go, but in here it used like get out of here. Am I understanding it right?

What does "spring something on somebody" mean? Does it have negative meaning itself?
"Spring something on somebody" is an idiom that refers to telling someone something important suddenly and unexpectedly. It has somewhat of a negative connotation because usually the receiver is stressed that they were told something important without any warning or time to prepare. Ex: My sister sprung on me yesterday that she is eight months pregnant. I can't believe I'm going to be an aunt in one month. Ex: During lunch, my best friend sprung on me that she is getting married in one week and wants me to be in the wedding. Now I only have one week to buy a dress.
