i think it was early saturday morning when i saw this on my facebook newsfeed. it kinda ruined my morning because it is both sad and true. and i can relate! i didnt know geometry has some sad concepts relating to life. didnt know that mathematics can be applied to human relationships..
how about the division symbol "÷" (obelos)? do u think its a sad symbol? those two dots are like two people being separated. they know each others existence, but they jus cant be together. ):
