It was DD's birthday on the weekend and I'm sending out thank you texts and just realised that one guest I don't have a present from. Would you mention it to the mum in case it's gone missing? I've already sent a text saying thanks for coming but wondering if I should casually mention it or not? It's not a family I know well at all so it feels a bit awkward, but if it were me and the present had gone missing I'd want the chance to look for it in case it was left in the car or something. Argh, awkward!!
