New Delhi, Feb 06 (ANI): Finding love and keeping it are a difficult task. Here are some norms for dating in the present age to avoid disappointing your potential partner. An annual academic survey developed by biological anthropologist and Rutgers University professor Helen Fisher has found that 36 percent of singles in their 20s judge a date by their electronic device, but they find it rude if their date is busy checking their phone on their first outing together. According to the survey sponsored by Match.com, 59 percent of men are turned off when someone texts more than once before a reply, followed by texting during work hours and using text slang.
