Two questions about DD

It's now more than a week since our first proper foray into punishment for DD violations, and Rose got 5 smacks with the hairbrush for not closing her computer at the agreed time.  They were not hard, only about 30% of full force.  She didn't like it and got distant for a few minutes, but afterwards gave me a hug and a kiss.  Not only was this a surprise to me, something that seldom happens just out of the blue, but she has been unusually affectionate ever since.

As for my own feelings, I am shy to reveal this, but it's certainly true that I feel more loving towards her and more proud of her when I exercise this authority.   Not right at the time, for I don't like spanking her as a punishment; but some time later.

Though I have been theoretically enthusiastic over DD for years, my surprise at this development shows me that I was not in fact quite so enthusiastic as I had thought.  Now, I am really beginning to be more confident and think it is going to do us some good.  Such a simple thing, how is that it isn't more widely adopted?

That's the first question, that I don't expect to get an answer to.  The second question is:  Last year Rose's room was disgracefully untidy and dirty, and for six months I had been asking her to tidy it, but with very little result.  Finally when one day she was absent for some hours, I did it myself, taking care not to throw out or burn anything that looked as though it might be something she would need.  It took me about four hours and I filled a large garbage sack with rubbish, almost all off the floor of her room.

Rose was very indignant and sulky with me for a long time over this.  In my opinion now, I should have spanked her long before it got to the stage of my having to do it.  I would still like to punish her quite severely as her conduct was really indefensible and very disrespectful.  She refused to apologise.  Is there in practice a statute of limitations in matters like this?

I recently read Christina and Jim's account of their beginnings in DD and let Rose read it too;  it included just such a delayed spanking; but the circumstances were admittedly different and Jim had not delayed out of timidity, whereas I did - mostly.  I feel diffident on account of this delay of my own.
