If they are anything like my mother ( who is younger,than them , and has just forgotten my daughter's 30 th birthday) they are possibly just getting old, and forgetful.
keep sending your card is my advice, and don't worry about reciprocation, as long as you know they are alive and well, that us the main thing.
( There is always the possibility, that their postie, is a lazy B, and us dumping their mail)
