FIL lives a 15 minute drive away. DH invited him over today to see us and his 15month grandson (he hasn’t seen since May). DH text this morning at 8am saying we was going out for lunch and did he want to join us or pop over when we was home. No reply. DH text again at 6.30pm to say he assumed today didn’t work and that we was putting DS to bed now. FIL has just replied saying “I’ve been sat at home waiting for you to tell me when you was home from your lunch, don’t bother me with a empty invite in future”
YABU - DH should’ve text to say you was home after lunch
YANBU - FIL is a grumpy old man
