+    Any interaction with another contract imposes a potential danger, especially
     if the source code of the contract is not known in advance. The current
-    contract hands over control to the called contract and that might do
-    just about anything. Be prepared that it calls into other contracts of
-    your system and perhaps even back into the calling contract before your
+    contract hands over control to the called contract and that may potentially
+    do just about anything. Even if the called contract inherits from a known parent contract,
+    the inheriting contract is only required to have a correct interface. The
+    implementation of the contract, however, can be completely arbitrary and thus,
+    pose a danger. In addition, be prepared in case it calls into other contracts of
+    your system or even back into the calling contract before the first
     call returns. This means
     that the called contract can change state variables of the calling contract
-    via its functions. Write your functions in a way that e.g. calls to
-    external functions happen after any changes to state variables in your contract,
+    via its functions. Write your functions in a way that, for example, calls to

     so your contract is not vulnerable to a recursive call exploit.
