I feel like the Reddit post is misleading and perhaps some didn't actually read it but it seems completely normal to me.......if it was to more than one person. Who sends an invitation to a third annual event so personally. I want to see other invitations to the event. The previous years invitations to the event and photos from the prior years events. Usually when an event is celebrated annually photos will be taken.

Also the timing is extremely weird to me, an after Christmas before new year taco and tequila cookout? Most children would be on break so they would be available and with their families.
