I've shared my Wi-Fi with a neighbour. Was this wise?

How safe is my online information, and will I be responsible for all his downloads?

This week's question

My newish neighbour knocked on my door the other day to say he'd been waiting weeks for broadband, and could he share my Wi-Fi connection, as it works in his flat. I gave him the password but am now worried about the implications. Could I be held responsible for his downloads? Are all my files and logins safe? It makes sense to split the cost – but is there a reason why I shouldn't share my connection?

What would you do?
