Go ahead. It's just a plate.

My mother always said there is no one better than your own family, so she used her china and silver every night for our family dinner. Once a week we would eat in shifts in the kichen (not enough room for everyone to sit together in there) and then it was every day plates (many of which were plastic). So in deference to her and to my upbringing I use mine on an almost daily basis too even if it's just me. Why not?
