Question: How come sometimes you remember things which are really not important like for some reason i can remember giving in a worksheet in nursery? It wasn't anything huge it was just something normal, yet i can still remember every detail. So why is this?

  Hi @boomitsgeorgia
  Great question!
  Memory is a strange thing. Sometimes we remember things like this which are really unimportant. I’m not really sure why this would be, but maybe when you were younger for some reason this memory kept cropping up, and so it became much stronger than otherwise it should, because you kept thinking about it.
  
  I don’t know whether this is correct though I’m afraid. I’d be interested to know what the truth is though!
