Meanwhile, she’s also been a pretty shitty friend to Ted as well. She gives him shit for never leaving them alone, but moves herself in to live with Marshall.
Then, the part that really proves Lily is the worst, is when Ted calls her a bitch on a voice message. She overreacts and gets offended and takes away his (and by extension, Marshall’s) Christmas.
Meanwhile, she doesn’t realize that while leaving Marshall was bad, she also left Ted and never apologized to one of her best friends for going.
I think ‘bitch’ is getting off easy.
