Here are the basic things you need to have in your bag.
Firstly, you need to have a mobile phone.
Sometimes people, including me, have several mobile phones.
I have a modern web-enabled smartphone and an old fashioned mobile phone for work that get a signal quite well, so I am always can be accessible.
Secondly, you need to have a wallet.
In my country women like to keep a small picture of any dearest person there.
I have an image what my niece drew to me.
Then, that's important and I always keep in my bag some cosmetics, because I like always looking well.
There are a chapstick, a
pomade, a mascara in my bag.
I never forget about my hand cream.
A small mirror is also very important to be found in bag.
What have I forgotten?
Some hygiene products, a comb..
And you absolutely need a headache pill to be ready to everything.
Ps. sure, the passport or another document of identification.
