2--We should shop for some souvenirs to bring back home to our friends.

1--I'd much rather we spend another day seeing the sights.

2--We can sightsee and buy souvenirs along the way.

1--Why don't we just buy souvenirs at the airport?

2--The airport charges way too much for souvenirs.

1--Our friends won't know the difference.

2--We will know!

1--The hotel has postcards in the lobby, I think.

2--Postcards are to be mailed not given as souvenirs.

1--Fine! Let's go to the museum gift shop.

2--That's a great idea.
