Hold that thought

Hold that thought: um momento, espera um pouco

(usa-se para interromper por um momento uma conversa)

“Katerina was telling me about her week when I remembered that I’d left our drinks behind in the kitchen.

‘Hold that thought!’ I said, and went off to the kitchen to fetch them.

A few moments later I returned.

‘Sorry, now, where were we?’ I asked, as I put the drinks on the table.”
