'I' and 'me'
I always remember the day I was taught to use 'I' and 'me' correctly.
I was 6 years old and school had been cancelled because of the deep snow. I had spent all day outside, playing with my friend.
I came in at teatime and excitedly told my Dad that ‘Susan and me made the most amazing snowman.’
‘No you didn't.’ was his reply. I was puzzled. We had. We had spent all day making it and I had the frostbitten fingers to prove it.
‘I did,’ I insisted.
‘Who made the snowman? Was it you or Susan or both of you?’ he asked
‘Both of us.’
‘If Susan hadn't been there, who would have made it?’
‘I would have made it on my own’" I replied.
‘Would “me” have made it?’ he asked
Finally, the penny dropped,
‘Susan and I made the snowman.’
‘Yes!’ he said triumphantly.
Most people seem to make mistakes using 'I' and 'me' when they are talking about more than one person. If you are unsure of whether to use 'I' or 'me', take out the other person and see which fits, as in the example above.
(I could get all technical now and explain about 'I' and 'me' both being pronouns that we use to refer to ourselves. Use 'I' when it is the subject of the verb, and use 'me' when it is the object of the verb or following a preposition (with me, after us, etc)
