Not what you are thinking 😉
I mean for messages - if a guy takes time to send you a long message - is it safe to assume he is happy for you to reply in a more lengthy way too?
Whereas a shorter message might indicate he is more strapped for time? (Or just hasn’t got anything interesting to say at that point)
Does that sound about right?
I try to mirror the message length to not be a pest who overburdens the other person with too many (or long) messages
(just for more info - he initiates a lot of messages and always!! replies very promptly )
