Can/Could for polite request and permission.
What is Request and Permission
"Hi! I'm Request. Call me 'Little R'! I'm all about asking others to do things—like 'Could you help me ' Remember: if a sentence wants you to take action, that's me!"
"Hey! I'm Permission, or 'Little P'! When you want to do something and ask 'Can I... ', that's me! I'm the key to getting yes/no answers for your actions."
What is Request and Permission
Hey! My job is super simple. I help people ask others to do things.
When you need someone to lend a hand, carry something, or give advice, I step in! Just use “Can you… ” or “Could you… ”—that’s my magic spell.
For example, “Could you pass the salt ” or “Can you teach me math ” I make it easy to get the help you need!
What is Request and Permission
Hi again! I’m all about letting people do what they want. When you want to go out, borrow something, or try a new activity, you talk to me! Sentences like “Could I use your phone ” or “Can I leave early ” are my special language.
If you hear “Sure!” or “No problem,” I’ve given the green light. But “I’m afraid not” That’s me saying “not this time”!
