too dependent on my phone....

yesterday, I went to my friend's room and by accident I left my phone there. when I got back to my room, I started freaking out cause I couldn't find my phone. I could've sworn that I put the phone in my bag before I left but it wasn't there. maybe to some people, their phone isn't top priority. but for me, I used my phone for everything and I don't have a backup for almost anything. The only calender I use is the one in my phone for important dates, all my contacts are in that phone, all my homework and assignments are all saved in it. Luckily, I got it back this morning cause it would have been a real disaster if I didn't find it.
