How well do you know your texting slang?
ISTR that ISTR stands for "I seem to recall." This acronym indicates that the person you're talking to remembers something, but with some degree of uncertainty.
In some cases (like above), people use ISTR even when they exactly recall the thing they're talking about. These people likely began their message with ISTR in an attempt to not seem overly assertive or pushy.
