Why did Ted freak out...
...when Lucy told him Martha had been living in the Catskills? She said "it's ok" and he said "no, it's not". Was it just because they didn't know she had actually been that close by the whole time? That's all I can think of. Seemed like a pretty strong reaction though.
Saying "I apologize" is the same as saying "I'm sorry." Except at a funeral.
