Have you ever looked at an email and thought, "I'll reply to this in 3 years time?" You probably haven't. It probably holds true for texts as well.
However, what you most likely didn't realize, is that 3 months is equivalent to 3 years in email relativity on the web-time spectrum discovered by Dr. Heinz Frankle. That same position holds true for texting, except that the three year equivalent is likened to a 15 minute interlude -- and just 5 minutes when it's with a person of interest who is of the opposite sex.
He's not a pleasant guy this Frankle, but this smart, debatably German, professor came up with some brilliant shit in his time.
