Do you travel in tubes in London or............

Eh, no, there's not really much to be scared off there. There's some strange people but there's usually also quite a lot of other, normal people, so need to be afraid. Unless, if you claustrophobic, I would advice not to use the tube during the rush-hours. It can be quite crowded. You should watch out for pick-pockets I think, especially when it is crowded.

I used to be very scared, but you soon get used to it. Follow the signs to make sure you get on the right train, then it is easy as they have maps inside the tubes and they announce each stop, so you know where you are. They can get very busy around 8-9am and 4-6pm so you can try to avoid these times if possible and it will be less stressful.
