I do like to text because I find it convienent, among other things. But I still understand and appreciate the importance of talking on the phone. Texting, just like aim or whatever, gives you an invisible mask. This means you either 1) say really harsh things because you have time to think about them or 2) you refrain from saying really harsh things because you can think about them. There are pros and cons to texting but you need to be able to realize that some conversations are not meant for it.
Besides you can't call people during school. :)
