Society says that toys (i.e. Tamagotchis) are for kids. Everybody follows what society says. I say, who cares what society says you can and cannot do. Do what you want, regardless of what anybody thinks or says. I am 26 years old, and I still play with Tamagotchis. I am currently running two Tamagotchi ID L. I take it everywhere I go and I even put them on the table next to me, so I can monitor them. I do get people telling me that Tamagotchis are childish and only kids play with them; however, if makes me happy, then let me be. Playing with them is not harming anybody. My dad asked me today if I was playing with Tamagotchi's and asked me what they do and if there are games on it. He picked it up, looked at it and pressed a button, then gave it back to me.
Here's a funny story. For Christmas a couple years ago, my family did Secret Santa. It's where we pick out names, secretly that is. Then we go and buy what they want on their wish list. I had asked for the Tamagotchi V4.5 green swirls edition. My cousin had gotten my name and went to Toys R Us and bought me the Tamagotchi I wanted, plus some accessories. Personally, I didn't think he was going to buy it, since he is like 30's and has to go into Toys R Us. So here comes Xmas eve and we are opening our presents. I get to mine and to my surprise, I got exactly what I wanted. The point of the story is, that after I opened my present, he had said how embarassed he felt to go into Toys R Us and buy this toy.
