Please tell me I am not being unreasonable here.
My dad has four children. An older son from his first marriage and then myself, another daughter and a son. My older brother (DB1) and my father didn’t have much contact until DB1 was in his late teens. There is quite a lot of water under the bridge and DF works quite hard to maintain a relationship with DB1. As siblings we have met him quite a few times but haven’t really got a meaningful relationship with him. DB1 has had endless problems with drink and drugs (been to rehab a few times. I’m not just talking about drinking in excess and a bit of coke at weekends)
I give all this as context as DF messaged me last night to ask if DB1 and his grandmother (no relation to us, have never met her) can join us for Christmas dinner. I am hosting. Myself and my sister have children under 5. According to DF, DB1 is sober and clean atm. We have heard this many times over the years. And that he has nowhere to go (Not strictly true as I know DB was originally planning to have Christmas just with his Grandmother). It is complicated by the fact that DB1 has been living abroad with a girlfriend so DF doesn’t see him often.
Am I being unreasonable to say guests can’t invite further guests 4 days before Christmas? Especially extra adults!
