Delta Delta Delta/Sigma Sigma Sigm

[DeltaLove87]

After looking at the website of Tri Sigma, I can't help but feel there are some real similarities between the two. Check out Tri Sigma's website:
http://www.trisigma.org

• Only sororities with three of the same letter
• Both mention "perpetual bonds of friendship"
• Both mention "a stronger & more womanly character"
• Tri Sigma & Tri Delta both have similar insignia that go on stationary. (I cannot find an example of DDD, but SSS has it right on their website in the top left corner)
• Inspiring high standards of ethical conduct sounds a little like broaden the moral & intellectual life
• DDD founded in 1888/SSS founded in 1898 (a mere 10 years later & involving a lot of 8s!)
• DDD magazine The TRIdent/SSS magazine The TRIangle (aka DDD's symbol)

I just feel like I am on the outside of some practical joke when looking at these similarities!
