Wallpapers

It's normal.

Every human expresses themselves differently, some do it by talking with someone, some do it with music (like me), some do it with art. So it's completely normal.

Ummm I may b wrong but I'm pretty sure it is in fact normal to express feelings thru art ie: wallpaper on a phone.

That's simple, you're used to waisting yourself and your computer too with crappy wallpapers which take some space.

I watch my fiance do the same with her Windows Wallpaper and it seems normal. I feel old but I would only use a cellphone for actual phone use. All of that excess crap is just better to do on a laptop anyways.
