I am very much annoyed by people who send me e-mails or instant messages with unecessary multiple punctuation marks like "?" and "!". I think it is ugly to the eyes and seems childish and immature. To me it is no different RECEIVING E-MAIL IN ALL CAPS.
A few days ago I made someone angry for saying that I do not like to see multiple punctuation marks with her correspondence to me. She said I was being paranoid.
Some people can be incoherent!
Is it wrong to have some standards to your communication? Some people just cannot accept feedback.
