Idiom expressing betrayal of resentment/hurt

[Judylight]

Hi everyone,

I have been trying to find an English equivalent to a Spanish expression (resollar/sangrar por la herida), which means to betray hidden resentment/hurt; the implication is that someone has been offended/hurt, they have attempted to hide their feelings, but the latter are inevitably exposed through words that betray the underlying emotions.

Any help would be greatly appreciated.

Cheers

What's the time period? If it is at the time of the hurt/insult, etc, we can use 'put on a brave face', which has the idea of trying to cover your feelings unsuccessfully, though it doesn't have to be through words alone.

putting on a brave face isn't always unsuccessful, is it?

Interesting question... It's almost like "wearing your heart on your sleeve" but instead "wearing your heart through a rip in your sleeve"
