you asked a closed ended question. they're great for gathering specific information efficiently.
closed ended questions typically result in brief answers. they're like a multiple-choice question with a limited set of possible responses. it's either option A, option B, or sometimes, none of the above. this is one reason of why she responded like that
the answer could also be exasperated by any personal feelings she has in that moment [tiredness from the trip], and not necessarily related to you..or maybe she was about to say something more then got distracted.
another is that her answer could be related to how she feels about you given previous interactions. it seems she is matching you, and not offering up more emotional information, which would occur naturally if she is in a higher level of compliance. if this matching happened in person, within the context of a RAPID response conversation, would you withdraw attention on her equalness? me personally, id be more likely to ask for more friendly compliance. sweet, howd the trip go, did it meet anticipatory expectations, or maybe you went in having none? what was your favorite part? im curious!
and yet another, the sometimes slow response time of text leads to a lot of personal deliberation and increasing of whatever her emotions are you are deliberately or in-deliberately building BETWEEN answers, leaving texters at a risk of amplifying negative or positive shit in her. again, think towards how youd behave in a rapid conversation in-person to say the right thing in the context of an existing slower thread with girls of equal or higher compliance, then work towards balancing it against thread cutting if you find shes lower compliance with you [or if shes equal/higher compliance and want to ramp up her emotions quick quick] and the time between responses is slow, thus decreasing the possibility of negative amplification. for example, moving POLITELY slowly through the initial texts with a lower compliance girl, will cause you to lose her - skip ahead to a thread cut
