One thing I like is attract / to attract / attracting attention. Any difference? 1. One thing I like is attract attention. 2. One thing I like is to attract attention. 3. One thing I like is attracting attention. I have seen all three structures. Are they different in formality? In case (3), would it be ambiguous because it is not clear whether it means I like attracting attention or something that I like, e.g. a movie, is attracting attention? Thanks
