SECRET SANTA

I was given my co workers name before Christmas, I bought the gift for $20.00 on Amazon, I’m low on money kinda struggling so I didn’t select fast shipping. The total ended up being $37.00 due to taxes etc . The gift arrived to my co worker on the 27th . I told him twice the date that it would arrive. That’s his response below . So after Christmas when work started back on Tuesday he posted on the chat who is his secret Santa because he is starting to feel left out. I didn’t respond because it was odd to me . Of course he knows who I am and the date I gave him. Then he got the gift on the 27th and he posted I’m good now on the chat , but never told me liked it or anything. So again today he posted who was my secret Santa ? Another co worker commented saying I had you , I hope you like the gift , he responded you are a good Santa etc . I don’t know if my other coworker decided to send him a gift also or they were just joking. What do you YALL think ?
