It's not the first time, where someone asked if I was taken and I replied,"Yes,but thanks for asking me!" . And then they asked," Can I have your number?" continued by "Just as friends". I hope some really are honest with their "Just as friends" reply. Because that's just complications waiting to take place unless they are really content with being friendzoned. I just said,"I'm sorry I don't give out my number often. But thank you for asking." And walked away.
