Family is concerned

[skitzo444]

About 2 weeks ago I deposited 25 dollars on pokerroom right now I have 450. My mom and girlfriend talked to me last night about cashing out 400. They are worried I will lose that money and they don't understand at all. I know they shouldn't be concerned with my money management. but I do not need that money right now and I am not risking all 450 when I play...such as sitting at a 1-2 table with $50. They still don't understand why I don't just cash it out. But for instance if I do and am left with 50 if I want to play a 20 MTT I have no chance of making the money back but with 450 minus 20 I can earn the buyin back with a 2-4 or 3-6 table. What should I say to them to make them understand? Do they have a point??
