• people who typ lyk dis on fb/msn/evrywhere
• rudeness on phones, on either end
• people who don't say anything within the first five seconds after I pick up
• people who repeat their sentence/question with different intonation thinking it will help the interpretation
• persistent callers - callers who wait over a minute in hope that someone will pick up + callers who call back after less than 5 minutes when they didn't get a pick-up the first time (I don't answer phone calls - they terrify me!)
• people who don't at least glance at me while I'm talking to them
• people who speak over the top of everyone else
• "you're so stupid, your going to fail that exam"
• "their going to there house over they're"
• people who give one or two word replies to long texts. I make an effort to write well structured texts with full sentences and good grammar.

I actually don't mind telemarketers - sure, they call at the worst of times, but if you're patient and calm, they know when to back off.
