Extension ???

Yesterday I was walking and met with one of the big bosses here.., I said hi, she replyed and also asked me about when's my contract going to end..., so I replied on the 12th of January, so she told me: "We can extend it, what do you think? Would you like to ?"............... Well, my answer was "Maybe..", but honestly is a deep and clear NO. I want to get back first, finish my university.., and do a lot of things that i've been planning long time ago. Also, I feel happy because of that, because I saw that what I've done here is good, if not she won't be telling me that........., thats a fact.
