Awww bless,his tweets are the best aint they ,ive noticed he has patches like this where he doesnt tweet much and they are most likely to be cos he's busy and any free time he does get he wants to spend with his family,he's busy all the time bless him but sometimes even more than others,I dont know this for certain,its just my thoughts.
Bet part of him will be sad bless him when les mis finishes as he has been part of it for well over a year or is it 2 ive lost count lol
