I like getting texts & sending texts, especially if it's just to simply check plans or something with someone. When they turn into longer conversations it gets a bit much.
One thing I find annoying is if I don't reply straight away, certain people will send another text asking whats going on or repeating themselves. This feels like an invasion to me as it's my phone to use when I want - not when they want me to. Half the time I don't realise I've received the original text!!
