"Have a ridiculously full schedule tomorrow with 17 meetings/engagements. You always pay a price when u come back from a trip," he wrote in his latest posting on Twitter.
"Long day catching up with a week's absence from Delhi. Mountains of pending files. Two journalists actually interviewed me on Africa!," he wrote in another posting.
The latest postings came after his meetings with Congress president Sonia Gandhi and Prime Minister Manmohan Singh to give an explanation over his "cattle class" remark after which he was told to refrain from making such comments.
Tharoor comment on his Twitter last week terming travel in economy class as 'cattle class' evoked controversy and arguments from all corners.
