Explanation of difficult points

1. "小……" and "老……"
"小……" (xiǎo) is often used before surnames or given names as a type of nickname [e.g. in Dialogue 1, "高强" (gāo qiáng) uses the nickname "小强" (xiǎo qiáng)]. Another common way of making nicknames is by putting "老" (lǎo) before one's surname. Usually this is used with older men, for example, "老王" (lǎo wáng).

2. "这儿" and "这"
"这儿" (zhèr) versus "这" (zhè): The first means "here", the second means "this". "这儿" is the same as "这里" (zhè lǐ).

3. 真
"真" (zhēn) means "really" and is often used before an adjective to signal emphasis.

4. 那
"那" (nà) is defined in this dialogue as "in that case...".
