we have along history of disagreements with DH family, they are all a little odd. HIs aunt (his mums twin) told us she would be down to visit this weekend and could she pop in. She sent a message saying she'll be here at 2pm, DH emailed back and said can you make it 4 oclock and lisad123 will make some dinner for you both.
Had an email back saying, yes 4 oclock is fine but will only be my husband coming as im going to see my son. 
I really dont know him well and when i have seen him he has given me the creeps but we accept him as his married to DH aunt.
I have asked DH to email back and say we would rather rearrange another time when we can see them both, and he has emailed twice and no reply (they always reply very quickly normally).
What the hell do I do?? Im going to have this creepy man at my house on his own, DH thinks he will just turn up and say never got emails 
Does anyone else find this odd?? Surely the aunt needs to eat too??
