Weather is looking great. So, we will have dinner in Katwijk tomorrow at one of the Beach restaurants. Please let me know if you want to join. At the moment there are 9 people that have signed up.

I will let you all know about the details tomorrow morning.

Hi all,

I want to propose our next social event for May 20^th. That’s not next Tuesday but the Tuesday after next.

I was thinking if the weather is good, we could go to Katwijk and have dinner at the beach. And if the weather is bad, we can do a potluck at my place. So, I will be checking the weather forecast and make a decision next weekend.

Please let me know if you would like to join. Then I know how many people will be there.

Met vriendelijke groet / With kind regards,

Dr. Sebastiaan Haffert
