What little or big things irk you that your DC's playdate guests/friends do or don't do etc?
My DC is 10..
I 100% know this is totally unreasonable but for some reason it really irks me when DC's friends bug me for food and drinks either before the food is ready, or continue to ask after having been well fed by me. It's always the same ones too! I assure you they will do this even when they've had LOaDS. I am a massive feeder and take great joy in cooking for them.
They are from homes where they are well fed and cared for, so it's not like they go without which obviously would be different..!
One of these lot also often arrives hungry saying they havent had breakfast etc. which makes me annoyed at their parents... though perhaps this particularly greedy one is bending the truth..!
