3 things you cannot leave your house without...  

I don't like leaving home without my cellphone. I never know when that could really come in handy. I also do not like leaving without chapstick. I hate when my lips get really chapped and I can't do anything about it. I don't like leaving my house without a purse anymore but I have done it. It just makes me comfortable having it even though I don't always use what is in it all the time.

Well, how can you leave your house without keys ,if you plan to lock the door after you:))
ow well but my answer would be my cell-phone..it's like missing a hand if i don't have it..second would be...err my wallet,yes.. i can't do anything without my wallet..and third..i usually don't leave without my cigaretts or at least a lighter ,if i have no cigs and i am going to buy some:)

I can't leave the house without a wallet for my money, my phone for contact and my deck of cards for magic. I always bring these three things because I don't feel comfortable if I don't have them with me.

For me I cant leave home without my mobile phone, home key and my wallet.

my wallet, my specs and my cellphone

Pretty easy, keys, phone, wallet. You should ask what three things besides the basics like keys wallet and or purse one can't leave without that might be tougher. I would say some medicine for my kid, asthma, and then I might be stuck. I bet there are people that can't leave without their smokes, make up, watch and things like that.

Hello my friend nikna88 Ji,
Well, for me it may be little different ones, apart, what you think, I will not leave my house without paying attention to :-
1. Security of the house.
2. All electrical safety mesures have been born in my mind and
3. I am prepared for all those works for which, I am stepping out of my house.
Have a great day.

I can't leave without my purse, keys, and cellphone. These always go out the door with me. No matter what I have to do or what else I am carrying out of the house, these 3 things will always be included. Can't live without them.

I never leave home without my cell phone, reading glasses, bank card and keys! I guess that is 4 things but they are always in my purse so I guess it could be counted as 1 thing too!

I can't leave without my room key and door key. I used to bring a bottle of water with me, and my cell phone.
That's the 3 things I have to bring with me when I have to go some where. I remember I before I always forgot to bring my room and door key, and it really gave me hard time opening my room, thank god my uncle have a duplicate on our house and my sister had a duplicate of my room. Because I allow her to get in my room even when I'm out.
