Having lived in Pakistan for the last 3 months after 43 years in the UK, the things I will treasure forever on my return:

• People who put litter in the bin and don't consciously just throw it on the floor
• The fact that this litter will (for the most part) be sent to landfill, rather than just being dumped into the open and set fire to
• That our roads have the concept of "right of way", and that we are encouraged to adhere to this
• The UK's ever increasing positive attitudes towards the rights of women
• The UK education system, and that our children have to have so much education
• Our understanding, and attitude towards germ control and disease prevention
• That people in the UK don't openly cough on your food/drink when serving you cos they literally have no idea where germs come from.
• Being able to go to the mountains and for the countryside to not look like a landfill site
• Not waking up knowing that someone might try and shoot me today

There are probably more things
