I have watched 16 seasons of grey's anatomy. But the first five or six seasons are my favourites.
yeah I heard the big cancer story was based on a true story
Izzie's cancer story? I didnt know about that. But glad she survived it.
I seen lauren and ben is happy
Hmm. The main part I like is the beginning of friendship. Omalley, izzie and meredith staying together and making their bonds stronger. The small fights and then patching up again.
yeah that was special they word things out 
Oh yeah. and lets not forget the legendry Christina and meredith's friendship. I never wanted Christina to go to Switzerland. These characters are so deep.
I like cristina and merediths best ten monments
I cry everytime when I rewatch the episode where they do the last dance. 
yeah the last dance was episode 16.13 that was cool
