What an original birthday present!
This can be a picture book.!
I have two daughters, 5 years apart, and all your illustrations and the evolution of feelings among you and your sibling made me think about my daughters. Their love-hate relationship corresponds to the siblings rivalry theory and has provided plenty of laughs and plenty of headaches too.
Hehe thanks ^_^ It doesn't meet my ridiculous standards for a picture book, not to mention I'd have to remember how to lay out a book as I've gotten used to just doing excessive vertical strips XD
I remember spending a lot of time trying to figure out this sibling rivalry thing, wondering how to avoid it, if it had something to do with age gap. A friend of mine was surprised that I get on so well with my sister now (and have done since I was in high school), she said she's 4 or 5 (or maybe it was 6 I can't remember) years older than her youngest sibling and they barely speak, she gets on okay with the one closest in age XD
After having my own kids and spending a bit of time trying to stop them from fighting, after a point I realised that it's one probably really efficient way to learn how to resolve disputes (with some tools provided as situations come up from us) and leave them to it XD Did you encounter a similar thing? :)
