I used to play with them all the time when I was little, up until they stopped selling V6s in stores. After that, I put away my collection and did other things. I got back into Tamagotchi after my dad died, when my family and I were staying with my grandparents. After a few months, we moved back into our house, and I put my collection away again. A while later, I felt like turning on my V4.5. I noticed that the date was almost exactly a year from the last time I played.
It seems like whenever I feel sad or lost (even if I'm not fully aware that I am), I turn to my Tamagotchis. I guess it just brings me back to when I was 8, when the most I had to worry about was making sure this little toy wouldn't die, and keeping my room clean.
