Dear Past Erin,

Under no circumstances should you tell your consin's new girlfriend about thrush and it's nasty affect on breastfeeding over tamales at Ol' Mexico.
She will pretend to listen, but actually try to figure out what thrush is while staring at the cilantro caught in your bottom teeth.
Oh, Past Erin, do you remember the days when you talked about things other than your baby?
Me neither.
Sincerely yours,
Future Erin
