Unit 7-3: First I annotated the phase '15 minutes waiting' as A and continue annotate all the way (including C and E relations internally), then I wanted to add the word 'about' (before the phrase) inside the Participant unit and I could not - I got "sibling error'. Only after I deleted all the internal annotation (C and E) I could add the word and then I needed to annotated everything all over again.
