It can be really hard for actors who have been together for six seasons to say goodbye to each other once the TV series is over. "White Collar" had a good run, but season 6 will be its final season. And sad to say, the cast and crew are packing up.

Filming for "White Collar" season 6 ended July 31, where the final scene between Matt Bomer and Willie Garson was filmed. It was also the last time the cast is stepping inside Neal's apartment.

Garson took to Twitter to share his sentiments about the final filming day. Garson uploaded a photo with Bomer and captioned it "Our last day together......I don't have words for this....rough rough day for sure......@MattBomer @WhiteCollarUSA"

We have all seen Garson in "Sex and the City," so he, more or less, knows how it feels to say goodbye to a show he has been part of for years. However, "White Collar" is different. He's been a major part of the TV show as a permanent cast member.

Bomer also shared his sentiments with TVLine, saying, "There's this undercurrent of I don't want to say sadness, but... What's the French word...? We're all having a blast working together. It's just like old times like it's always been, but underneath it all, we all know that we're going to have to say goodbye. We're all dreading that moment because we have been such a close-knit unit for six years. So it'll be sad to say goodbye. All good things must come to an end!"

Neal and Mozzie's friendship was truly memorable, it would be interesting to see how each of their storylines will end.  CarterMatt.com states: "Given the overall tone of the show we cannot imagine there being a sad ending for any of the main characters, but we also wouldn't be shocked if the ribbon was not altogether tied up. Sometimes, open-ended finales are fun, even if they do drive some people out there a little berserk."

While fans of "White Collar" are sad about the show's final season, they still have six episodes to enjoy how the characters will find their happy endings. Nevertheless, fans of the show should feel really happy that they will still have six episodes, given that the season 6 renewal came late.

"White Collar" Season 6 will air sometime in winter 2014.
