Honestly, a lot of the videos and photos that they post about it look as though they have, themselves, been shedding some I-know-it’s-the-right-time-but-I-don’t-wanna-go tears, so Ackles and Padalecki probably know exactly what they’re talking about when they say that there’s no crying allowed.
As I mentioned before, both of Supernatural’s leading brothers (along with Misha Collins, who has played the angel Castiel since Season 4), in the almost two years since the end of the series was announced, have spent a decent amount of time letting fans in on their feelings about the show ending.
