I think I've just committed a social faux pas 
One of my twins had to take a plastic milk carton in to pre school today for a project .
I'd completely forgotten about it until we got to the gates .
I'm stood with three other parents ; when it became obvious that myself and another of the parents had forgotten the milk bottle .
One of the parents said they had two and there would probably be other spares .
I politely asked if she would mind if I took her spare one to give to my DS and she seemed fine with it .
Out of the corner of my eye I saw the other parent with no milk carton shoot me a look . It dawned on me that maybe she thought I was being a bit grabby? By asking the other parent for the milk bottle.
As it turns out , another mum turned up with another spare and so the other parent got one too .
Was I rude ?
