What should i gift my parents?

IF they won't let you pay them rent then I'm sure they wouldn't want you to spend a lot on any kind of gift. I agree that a dinner out would be nice.. or tickets to a show if there are any in your area... but maybe going out of your way to have dinner waiting for them (a special one that you make yourself complete with flowers and nice tablecloth etc.) would show more of a personal touch. Sometimes the most valued gift is a letter to each expressing your heartfelt thanks and love... telling them what they mean to you. Why not do this along with a personal dinner (don't forget the candles) that you take hours to create?

You should probably gift a saree to your mom on her birthday and may be book a dinner or lunch in a nice restaurant for the wedding anniversary.
