A simile is comparing something with something else using 'like' or 'as' (for example - I swam in the sea like a fish or my room is like a tip).
A metaphor is a word or phrase that compares something with something else (for example - his heart is metal or my room is a tip). Hope this makes sense!
1. The road was as curvy as a snake - Simile
2. My mum told me that my room is like a pigsty - Simile
3. Mike is like a scared kitten as he enters the haunted house - Simile
One reason is that say someone is on bed rest/in the hospital not allowed to move, it can make them very week and make it very hard for them to walk again.
