Irritating

Dad asked me how to spell my cousin's name. Problem is I've no idea cos we always call her Eileen, but there's a high chance that it is not spelt that way cos she does not have an English name in the first place. It's probably some ethnic spelling like Ee Lin/ Ee Lynn etc. Anyway, irritating thing is that this is not the first time he asked me how to spell the name, and it is not the first time I told him I don't know how to spell the name. When I told him I don't know how to spell the name he said I'm being selfish. What's so selfish about not knowing how to spell the name?!

S.T.U.P.I.D.
