We (me & siblings) made a surprise celebration for them last Saturday. We show them this video during the night. (This video is a surprise too). Glad that the surprise really works! Planning behind their back for about 2 months. Contacting with each other via email (the email thread is super duper looonnggg) so that it will go unnoticed and it totally pays off.
I cry each time I see this video
As I am writing this, they will be on the plane to Moscow till 18 May. My pray is with them.
