Do not worry. At my college, there are a lot of Middle Eastern students, some from overseas, and I would say that there is a lot of respect for diversity among the students and a pretty friendly atmosphere. So I would never just suspect someone of being a terrorist. :)
Hopefully I'm so lucky to have a friend like you , leyna and others here :*
Next week I'm gonna have a trip to the sahara desert
Hope one day we all travel together there and play card games ^_^
