The background is that my dad is having chemotherapy and db and sil who live abroad are coming over for a few months to help out which is a very good effort by them.
They are arriving at around 11pm and picking them up from airport would mean I wouldn't get to bed until about 2am. DH and I have to get up at 6am to go to work. Then I have to come back and look after my toddler dd. I'm not a good sleeper anyway and it's likely I wouldn't sleep at all that night. I have a stressful (and responsible) job which will be particularly stressful that week for various reasons. I'm not someone who copes well without sleep.
The last time I spoke to db he did not appear to be expecting me to pick him up and spoke about getting a taxi (not expensive).
The problem is that my dad has been on the phone to db saying I will pick them up and is saying to me that I should as it will be nice for them. (I haven't spoken to db myself again). When I said I didn't want to do it, he compared me to sil, saying she is making an effort and implying that I am being lazy/selfish by not wanting to do this. He says it is only one night/day and I should do it for him (who is ill with cancer). He is being quite passive/aggressive about it imo. But it seems to be a big deal to him rather than to db who doesn't seem that bothered. (Although father may now have made him bothered)
I feel guilty and upset but at the same time the prospect of missing a night's sleep is making me feel ill and really stressing me out.
So, am I being an unreasonable lazy/selfish cow and should I just do it or would I be justified in saying no?
