I have seen several incidents where celebrities did not even let a small child near them, and I have also seen some wonderful examples where a very good celebrity pulled people close and took selfies with them. In some cases, a celebrity has gone so far as to beat up a fan. Actually, everything is a matter of mentality, but a celebrity should never behave rashly. If he wants, he can take legal recourse and explain it nicely. On the other hand, a fan should always show respect and love for celebrities.
