Hi Leon,
It was a pleasure meeting you last night! The event was so well done and it was exciting meeting such an amazing group of people - I hope you are enjoying a well deserved break after pulling it all together!
Also, I don't know if you saw this yet, but someone just bought a $375k first edition pokemon booster box and it wound up being fake! The Gaurdian covered it and I remember you mentioned being a big fan. Hope you have a great rest of the week!
Cheers,
Bob

Hi Leon,
It was a pleasure meeting you last night! The event was so well done and it was exciting meeting such an amazing group of people - I hope you are enjoying a well deserved break after pulling it all together!
As I mentioned last night, I'm just starting my engineering career and would love to learn from successful people such as yourself. Please let me know if there might be a time you are free to grab a virtual coffee over the next week or two. Before 9am or after 5pm tends to work best for me, but happy to accommodate what works for you. Thanks!
Also, I don't know if you saw this yet, but someone just bought a $375k first edition pokemon booster box and it wound up being fake! The Gaurdian covered it and I remember you mentioned being a big fan. Have a great rest of the week!
Cheers,
Bob

parent child
<section>
<article>
