The place of too

You can choose either way.
Those who are fond of commas might do it this way:
"I, too, am proud of myself"

Rag's right, Mil; though the trend is away from the comma except where it's needed for meaning

Incidentally however, there might be a slight difference in meaning of the two sentences: Thbe second could imply that there also are other matters of which I'm proud

Actually the intent here is meant that I am proud and others may be proud also.

Yea Rag I understand; but thought Mili might find my incidental observation of interest
