Have you ever 'experienced' [='suffered'] the loss of a pet?
That was one of the worst days I've ever 'experienced'.
The job calls for someone who is more 'experienced'.
(..) By far. Nothing else came close. It was the worst, most painful, mind-destroying, horrible moment... - OK. ...I have ever experienced. But once I realised the problem was not you, but within me, I found inner peace and was able to harness the flow of the universe. (..)2011 Kung Fu Panda 2
