Jon Lester thanked everyone who wished him well on Twitter

Jon Lester signed a deal with the Cubs late Tuesday night, despite Red Sox fans' hopes that he would return to Boston.

Lester has been busy during his first day in Cubbie Blue, replying everyone—no, seriously, everyone—who tweeted at him about his decision to sign with Chicago, even the haters.

His timeline is just full of countless tweets like this.

He'll probably end up with blisters on his thumbs from all that tweeting, but spring training is still two months away.
