Well well, I just realized that this page has a wonderful forum for sharing out member's ideas as well as doubts about love. Anyway I really appreciate whoever there proposed to make this forum. Just a doubt that I haven't actually experienced yet but I am sure it will cause me some trouble when I will have to deal with it. Up to now I have discovered one nature of me: whenever there is a physical problem (not necessarily problem given in lectures, it can be anything including statements or arguments in textbooks) that I found myself hard to comprehend, it will keep bothering me or rather haunting me until I could find the answer. It's so irritating that I would usually keep pondering about it while eating, taking a bath, walking outside, and others daily activities. In such situations I would also usually feel really hesitated to hang out with friends or to come to a friend's invitation. And this is the point where I came to imagine, what if I had girlfriend and she asks me to go out while such situation described above occurred. I have never experienced that though, but I can already imagine that even my girlfriend won't be able to divert most of my attention on this occurring physics problem. I would like to know does the same situation where there is unsolved problem that keeps haunting your mind until solved happen frequently (it actually frequently happens to me) to any one of you? And if this were to happen to me while I have got girlfriend asking me out, any suggestion? Sorry if this is a silly question.
