When can you replace So do I etc, with Me tooí?
Me too works quite well in simple exchanges such as:
* 'Iím hungry - Me too.' OR 'So am I.'
* 'Iím feeling very sleepy.' 'Me too.'
* 'I think Iíll go to bed.' 'So will I.'
Itís not very common as a stand-alone phrase with other pronouns, apart from You too? as a question, registering surprise, as in:
* 'I failed my maths exam.' 'You too? So did I!'
We would be unlikely to say: He too or Her too or They too, although we can use this construction if it is part of a longer utterance, as in:
* 'Maggie couldnít go and he too discovered that he was unable to attend the December board meeting owing to a prior commitment.'
Note that the converse of Me too is Nor me or Me neither:
* 'I donít fancy climbing to the top of this mountain this afternoon.' 'Me neither.'
* 'Iím not going to Janeís party on Saturday.' 'Nor me.'
Note that the so construction is used to agree with a positive statement and the nor or neither construction is used to agree with a negative statement. It can be used with all tense forms and all modal verbs, so you need to be careful to select the right auxiliary verb or modal. Consider the following:
* 'I canít swim.' 'Nor can I.'
* 'They shouldnít have said they could help him.' 'Neither should I.'
* 'We stayed at the Shangri-La in Penang.' 'What a coincidence! So did we.'
* 'Marjorieís going to live in Edinburgh Ė near the Cathedral.' 'Soís Jack Ė opposite the National Gallery.'
* 'I hate travelling all the way to Scotland by coach.' 'So do I.'
* 'I was so tired by the time we got there.' 'So were the other passengers.'
* 'We havenít forgotten that itís Sidís birthday next week.' 'Neither have we.'
