Final answer:
Chris may be frustrated with the phone calls because they interrupt his personal schedule, could be deemed unimportant as he is resistant to structures he does not agree with, or because his serious approach to phone calls is not reciprocated. Misunderstanding or conflict resulting from the phone calls can also contribute to his frustration.
Step-by-step explanation:
Understanding why Chris was frustrated with the phone calls requires us to consider the context provided. Chris may have been weary of and resistant to the educational system due to prior negative experiences, as indicated by his departure from formal education and the pursuit of his intellectual interests independently. This frustration could stem from a variety of factors. The provided context does not specify the exact nature of the phone calls, but we can conjecture reasons based on common issues related to phone call disturbances, such as: the hectic nature of personal schedules, decreased willingness to be interviewed, increased use of private numbers making it difficult to identify callers, or a simple desire for privacy.
In light of the scenario where Noel is decisive and not panicking, the importance of the nature of the calls is emphasized. Possibly, for Chris, a similar situation where proactive measures had to be taken was misinterpreted as disruptive, as indicated by Tracy's comment on 'frantic messaging and over-the-top language'. This suggests that Chris's frustration could be due to a misalignment between the seriousness with which he takes the calls and the response he receives.
Lastly, drawing parallel with the situation with Andy and Lucas from the reference provided, where phone calls lead to misunderstandings and conflict, could serve as an allegory; perhaps Chris's frustration emanates from the consequences of phone calls creating undesired outcomes amidst his attempts at decisiveness and problem-solving.
