I do not have a car and am unable to drive, nor do I know anyone on whom I could rely for transportation at such short notice. But the lady under whom I am doing the internship just sent me an email and mentioned that if I had a car or transportation that I could go to events with her, but the events would often be on short notice, e.t.c., and I just know I am not going to be able to do that because I do not have reliable transportation (and the bus is not reliable because it only comes at certain times, only goes certain places, and you never know how long it will take to get from point A to point B, not to mention that I can’t afford to keep paying for the bus). So what should I tell the lady? I just don’t want to sound like I am not willing to do things…how can I tell her that I really don’t have the means to be able to travel to events, but still be polite about it? Like just what exactly do I say? Keep in mind that she emailed me, so I would be emailing her back.
