Hello everyone, I hope you all have a nice day. I’m having some troubles in English. Could someone please help me?
1) I don’t understand the phrase: “red brick” in this sentence:
“It was the only UK university to receive its charter between the wars, in 1926, and has long enjoyed a reputation as a sound and quintessential red brick institution on an exceptionally beautiful campus.”
2) I don’t understand the phrase: “sweet paper” in this sentence, neither:
“No, the silly thing was that everywhere was quite clean but people were dropping their sweet papers and empty drink cans on the ground because there wasn’t anywhere else to throw them.”
Thank you very much for reading my questions, and answering them!!!
Best regards,
Loan

1) http://oxforddictionaries.com/definition/red-brick : "red-brick : (of a British university) founded in the late 19th or early 20th century and with buildings of brick, as distinct from the older universities built of stone."

2) "sweet papers" are the small pieces of paper that sweets (i.e. candy, confectionary) are wrapped in.
