Sunday Brunch

It is not tacky if you let people casually know that you will be gathering at a specific place the next morning and if they would like to join you, they can, but there is no pressure to attend (we are going to have brunch at .... If you can join us, we would love to see you.) If you issue a more formal invitation (Please join us for brunch on Sunday), then you would be responsible for paying.

So I shouldn`t give out simple little invites?
