Does the included Feynmann diagram makes physical sense ?

I intend to use this diagram: http://ift.tt/2iV9xvd

on my wedding announcement. It is a cheesy metaphor for my SO and I interacting from a distance, and then closely enough to have a child (the first escaping photon) and then the wedding (the neutrino/antineutrino anihilation).

I want to make sure there is no stupid mistake here, and that the diagram abides by the actual laws of physics.

It's a plus if this exact interaction between an electron and a positron is improbable: after all, us meeting etc. was also widely improbable.

Any info on this particular interaction being relevant in any way to any actual physics exepriment would be nice to have.

Thanks in advance :)
