Luke: Hey, just a quick question - will you be coming on Saturday?
Rob: Well, I'm thinking about it but to be perfectly honest this sounds a bit awkward...
Luke: Why so?
Rob: It's your son's 2nd birthday and I don't even have kids...
Luke: Dude, don't worry, it's not that kind of party - we are inviting all of our friends. Not only the ones with families and kids. 
Luke: We want to make it a pleasant afternoon with friends - just to hang out with you all :)
Rob: Well, if you put it that way it makes much more sense :)
Luke: Awesome - so I can count you in? We are planning the food and stuff.
Rob: Sure, I will be there. 2 pm?
Luke: Yeah, but don't sweat on being on time - we will have people coming and going all day. Hard to find a good time to suit 5 families with kids ;)
Rob: Lol, I would think so :) See you on Saturday then!
Luke: See you!
Rob will come to the birthday party of Luke's two-year-old son on Saturday around 2 p.m. Luke invited also 5 families with kids, but wants this party to be pleasant to all his friends, not only the ones with kids.
