Ready to go!

My youngest son and one of his pals in studies minutes before my boy had to defend his thesis to achieve his bachelors in physics ~ he did this well and passed his tests!
His friend here will present his in 10 days from now, fingers crossed all goes as well. Both continue studies for their Master degrees and I'm pleased they do!

I can hardly believe already 4 years have gone bye since he started off at Leiden University and moved out from my house
