Don't give somebody a fitness tracker...........
Unless that person has specifically asked for one. I laughed when the irritating Viv gave her the Fitbit, because my husband gave me one last Christmas.
He had specifically asked for one, so I got him one. I never expressed any desire whatsoever to have one, and absolutely DID not want one. But that's what he gave me. I think my look of WTH? And sheer disappointment let him know that the gift was a bust. I was (and still am) recovering from knee surgery, so the idea of 10,000 steps was a joke.
I wear it because he gave it to me, but I never pay any attention to it, and if I lose it, I won't care.
