Your mom buying a Rakhi for Alexa is absolutely hilarious - I can only imagine her excitement at finally meeting her "future daughter-in-law" only to discover it's a cylindrical device that occasionally mishears everything you say. The fact that she's already emotionally invested in this relationship means you're probably going to have to stage the world's most awkward breakup with a smart speaker. Maybe you could tell her Alexa had to move back to Seattle for work?
