Saying, 'He died when she was seven. They didn't go to the funeral.' Isn't really info dumping in my opinion. More brief telling. The more telling you do is when it becomes a dump.
I make standard rules for myself. Inevitably there are times when you must 'info dump' or simply 'tell', to get across why someone acts the way they do or so the audience can understand your magical world better or whatevr. I limit myself to 1-5 sentences, and often play with the wording to make it as concise as possible. Only include information that is necessary for the scene. Don't drabble.
Example of an Info Dump:
We would have picnics every summer along Loch Lomond and sing the song to remember my now departed father who drowned after a crooked policeman discovered that he was about to be turned in for supplying drug lords. The policeman was Italian and came from a wealthy family. Some say his father was apart of the mafia. We found my father's body, eight days after he disappeared along the banks. We could hardly identify him; he was so badly decomposed. The policeman's wife, Janice, said it was God's punishment because we built our house over a mass grave site, but we didn't know that until excavators came and found fragments of human bone. I was seven when he died. I wasn't able to attend his funeral.
So maybe if this was a real excerpt from someone's story all these things would be important. A crooked police officer who's father was apart of the mafia. A mass grave site. Loch Lomond. Janice. But no one gives a hoot about a lot of these things right now and besides the paragraph is horribly constructed
I really jumped around up there.
Keep to what's important, and in your example you did. You kept it short with minimal information. Just what was necessary for the scene.
An example of 'telling'/'info dump'-like scene that's acceptable would be:
Dr. Bennett always hated Evon for his debauchery and aloof attitude. If he laid a hand on his daughter again, he would do what he should have done ten years ago--kill him!
In this short segment you can draw quite a few conclusions: Evon isn't a very moral guy; his aloof attitude shows that he's not bothered by his past. Dr. Bennett is an over-protective father, he's moral, but intolerant hence him having the desire to 'kill' Evon because he had 'touched' Dr. Bennett's daughter ten years ago.
Short segments like these are fine because they're really not an info dump. I mean, one could take it that way because
it is 'telling' rather than actually showing, but it's short and acceptable and you can gather quite a bit from it.
Using the right words can cut a segment like this in half. Instead of saying all the immoral stuff Evon did, using one word: debauchery, basically wraps up his past. He had a lot of a women--end of story--no need to delve into where he picked them up or how he treated them; how long he stayed with them etc.
So basically, when you have to 'info dump', being picky on your word choice and limiting yourself to what's
most important for the scene disguises the actually telling that's going on. Sometimes you can info dump by using radio-stations, newspapers, television stations, voice-mail recording, medical records, diary entries etc. to express something that's happened in your world, but again it's important like I said before to keep these short and concise.
