I just received a message telling me about an error on one of my blogs. The person told me I had used “me” when it should be “I.”
Sometimes it can be tricky to determine if you should be using “me” or “I” in a sentence. Use the pronoun “I” when the person speaking is doing the action, either alone or with someone else. Use the pronoun “me” when the person speaking is receiving the action of the verb in some way, either directly or indirectly.
Most people have no problem at all knowing which pronoun to use as the subject in a sentence.
I went for a walk. 
Debbie and I went for a walk.
It doesn’t change when there are two people.
Me and Debbie went for a walk. 
If you remove the “and Debbie,” you can easily see that it sounds silly.
Once the pronoun is moved to the subject of the sentence, it evidently becomes trickier.
Would you like to go for a walk with me?
The predicate or predicated personal pronoun is me.
Would you like to go for a walk with I?
That just sound wrong, doesn’t it?
…you should use the object pronoun “me”. In each sentence, “me” is the object of a preposition.
It doesn’t change when another noun is added to the sentence.
Would you like to go for a walk with Debbie and me?
Would you like to go for a walk with Debbie and I?
The simplest way to see whether you should use “I” or “me,” is to remove the “Debbie and.”
Would you like to go for a walk with I?
Removing the “Debbie and” makes it obvious.
Should you correct other people’s grammar?
It’s annoying. If someone tells you something and you interrupt to correct the way it is told, it really sucks the fun out of a conversation. And frequently the corrector is incorrect.
I just love sanderlings. Those are sand pipers.
Aren’t the terns funny looking? Those are sea gulls.
Not an enjoyable walk on the beach. Personally, I don’t welcome the argument. You can call them whatever you want.
There is actually a form of OCD (obsessive-compulsive disorder) called Grammatical Pedantry Syndrome or GPS. Do you have GPS?
I appreciate it when people contact me to let me know I have an error. It happens.
In this case, I had used the pronoun correctly. But if one person thought it looked wrong and went to all the effort to let me know it was wrong, there are probably more who also thought it looked wrong. So I just took the offensive sentence out.
