I find these things hard to judge and am always worried about seeming rude. My boss is giving me a lift and has told me what time she will pick me up but she is often late to things and I also feel like we should add at least 15 minutes or half an hour onto the journey time so she would need to pick me up earlier. WIBU to suggest she picked me up earlier when she is already doing me a kind favour? And how do I phrase that over a text?
