I can totally relate. I know it's tough for most older people to understand, but for us, texting is perfectly normal and there's nothing wrong with it. I also don't think it inhibits or damages in-person communication. I have no problem talking with people face to face - it's just phone calls that irritate me. I can express myself much more in-depth and clearly via text rather than talking on the phone, and I can also say things that I would probably be too embarrassed to say when talking.
For my boyfriend, myself and most of our friends our age, phone calls are reserved for emergencies or for when you need to communicate something quickly and want to make sure the other person gets the message before it's too late (for example "the meet-up is in front of the cinema instead of the restaurant, see you in 10" or something).
