Stuck in the Middle !!!

Consider yourself lucky that you're allowed to hang out with him like the way you are now. Many, many families do not even allow that much. I know in our family, like PSquared explained, engagements mean nothing and we cannot even have unnecessary talks over the phone.

Your in-laws are okay with you guys hanging out but many many many Pakistani families are not. And that is important to keep in mind for your future, your sister and for your parents. :)
