I don't cry easily now, the antidepressants I am on seem to dry up my emotions. We have a very sick son-in-law (terminal cancer) and I used to spend hours crying about it. He has no living parents and DH and I are the closest thing he has to parents and we love him dearly.
I don't cry over world events as there's nothing I can do about them so I try as much as possible to put them out of my mind.
I still think about Aberfan and I remember a couple of names. Sophie North comes to mind as I seem to remember that her parents split up after she died. RIP little ones
