DS2 is at college studying furniture making. Doing pretty well now. He is intending to carry on next year to do the next level and probably the years after that to level 3. BUT... he has now become interested in something different and having found out that there are some local businesses he wants to ask if he could go and have a look. How would you go about wording this? Would they not be interested as he isn't studying their 'subject'?
