I can take several days to reply to a person's text (usually just due to pure laziness) and I expect them to be totally fine with it. But god forbid if someone else takes the the same amount of time to reply to me. My usual thought process is as follows:
"oh my god do they hate me they definitely hate me I have to move cities now oh god what if I run into them on the street that's going to be so awkward would I acknowledge them or should I ignore them..."
