I think you need to understand the difference between "is " and "am"
'I is the vine' does not mean 'I am the vine'
please show me the difference
Once again, is and are simply are two ways of saying the same thing. They are not interchangeable because one belongs to “I” and the other belongs to “he/she/it”. You are thoroughly misapplying them. You are the only person in this thread who has no idea what I am saying here.
