Answer:
Similes:
1. And your memories, they hang like a picture
2. You'll always be just like a sister
3. No one I knew stood half as bright as you
Metaphors:
I am unable to find any metaphors in this poem.
Step-by-step explanation:
Similes:
All three of the sentences contain the word "like" or "as" which are the defining words of similes.
Metaphors:
If you look closely every sentence that is comparing something happen to be similes since they use the words "like" or "as", therefore there are no metaphors.
