You see... they used to rub each other up the wrong way. Cooldude would enjoy teasing Miss Tanzi, and she would react with a nasty,cutting remark.
I believe the relationship between siblings has alot to do with how the eldest deals with the issue. The eldest is more mature and able to restrain him/herself when their 'fruit' wants to explode off the tree!
And.... Cooldude has really been instrumental in turning this volatile relationship into something very sweet.
I'm very proud of you Cooldude..... well done!
