My ex-DP and I invited my close friend and her husband to afternoon dinner one weekend. I can't remember why, but a colleague of mine also came over. My ex had never met him, nor had my friends. I have no idea what I was thinking, but I think and I must have felt sorry for him as he was lonely and I did have a right laugh with him at work. I thought he was absolutely hilarious and my friends coming to dinner also are, so I must have extended the invite when discussing weekend plans, thinking they'd all get on.
He didn't live in our town, so was planning to drive here and back again.
He turned up, got absolutely sloshed, insulted my friends with his "banter" then while we were chatting in kitchen after dinner, he disappeared and I found him passed out dribbling and snoring in my living room, taking up my entire corner sofa. We couldn't rouse him (three bottles of red put paid to that). So we had to spend the evening in the kitchen diner with my friends and we had to go to bed early after they left.
I got up early the next day to let the dogs out and colleague had already left. My friends and my ex thought he was an absolute bellend and they never let me live it down.
In hindsight, I was his only proper friend at work. Everyone thought he was weird, I personally found him an absolute hoot to work with and he was very good at his (creative) job. Great workmate, shit houseguest. 😂
He recently found me on Instagram, I'd not seen him in over 15 years. His posts are let's say... odd. I still have a fondness for him though, I like people who are quirky / bit weird by usual standards. I just won't be inviting him over again.
