One of the great bonding things in travel is shared conversation about children, even when language is limited communication is still possible.
In my hotel room the lady who delivers my laundry waits as I write out the ticket for today's load and notices my breast pump equipment. Baby? She say's, I smile and show her my baby's photo. She say's her's is 2 months old, smiles again. We part ways, both happy to have discussed our babies.
