[Excerpt] As children, we are curious —pointing to anything unfamiliar and asking questions. We have few, if any, inhibitions. As adults, we learn to censor our queries, feeling uncomfortable with anything unfamiliar. This is true when we are faced with new technologies. It is true when we are faced with tackling new projects for which we may not feel prepared. It is often true when we meet people who speak a different language or come from a different culture. It is human nature and not unusual, therefore, to be concerned about interactions with people who use wheelchairs, who are blind, who are deaf, or whom we find difficult to understand. We may be concerned that we will say the wrong thing, ask an inappropriate question, or unintentionally offend. We do not want to appear uninformed or insensitive.
