Lawyer charges for email answer?

[Caleb Heimsoth]

For people who use lawyers or are lawyers themselves, I'm just wondering if it's normal to be charged for simply responding to an email? Usually these emails are simply one or two line responses or answers (that's all they really require), but it makes me question if an email that takes 5 seconds to type is worth the money I'm charged. If this is normal, than I understand completely, I just want to see if that's the case. Part of me thinks you should only be charged for legal work or legal research, and these short brief emails should just be included in that, but I could be wrong. Any responses are appreciated. Caleb
