Hey dear brother. Right, its long time since we talked, thanks a lot for stopping by. I will start using #mathematics as one of my tags. How is everything? How is your family?

I'm OK, thanks; finally the summer holiday has started :-)
That means I can write more of what I want to, without a day-job getting in the way!
I may even start co-writing with my daughter, who is always full of joy and just one more year in primary.
How are you?

I am all good dear brother. Thanks a lot!
