I'm going to ignore a one night stand afterwards
Are you trying to change and be a better person?
I don't like to kiss and hug in the morning. Do you know that in some countries this is an important sign of love and respect?
I understand that you had a one night stand. It was wrong for you to have sex with someone you didn't care for. You don't have to kiss and hug, but you should at least be cordial.
Those countries must be very happy. I wish this was the norm everywhere because I'm not the hugging type.
You can always tell the other person afterwards that you don't want to do those things. Sex is enough and you don't have to stay just for cuddles.
