Makes me happy? It can be. I'm a very nostalgic person, and as my expect this remember my "withouth responsabilities" moments.
I've got a bunch of Tamagotchis when I was child, mostly are cheap versions with 12 pets or more.
But now I have V5 because my girlfriend found my old Tamas when I was cleaning my room and she wanted one of them
Now, my V5 sounds each morning and makes me feel better, thinking in the time can preserve people personalities, not always force to change them (this mean have I child mind? :S).
Hahaha, peoples think those things are for childs, like Pokémon, but I have 21 years old and this is not a problem, I don't care what people thinks about me, if people wants me, they will accept as I am with my likings.
Deep thinking I believe, hahaha.
Cya!
