I don't mind the texts. I answer, or not, as I have time and inclination. My parents know that if they text after hours, not to expect a quick response. And, I would much rather a quick text than to have to deal with a phone call!
Honestly, I prefer texts for communications about things that I need to know. Like Susie won't be here Friday or I need to pick up early Wednesday. That way I have it in writing and don't have to rely on my memory of a conversation at pick up.
