There are many times I run into conversations like this:
Waitress: Would you like some water?
Me: No thanks.
She walks away for a second, then comes back
Me: Actually, could I get a cup of water please?
or
Friend: Do you need a hand with all that heavy luggage?
Me: No. thinking for a few seconds... Well, actually, would you mind carrying this bag? It is pretty heavy.
It seems like "la verdad es que" is a mouthful. Is there a short phrase common for situations like these?
