Help me..?

Hey.. Sorry.. I've been kinda busy lately.. But I'm back and I need to ask you a question. Am I the only one that feels like I should be responsible for anything that happens to my friends? Well I feel this way because.. I don't know. I just do and I don't think I regret it. Hahah my friends say Im like a "mom" to them. But the "fun" kind of mom. They say I listen to what they have to say and give them advice. But in my opinion, I would make an awful mom. Because I think Im way too nice with my friends. I spoil them too much. If I keep this up, I think my chances to be a good mom will drop from 50% to 10%. And besides, what kind of mom acts like a 5 year old? When my friends call me "mom" I get mad. Not because they're calling me mom, but because I'm kinda disappointed in myself for thinking so negative. So is it just me or do some of you feel the same? It's not that I'm "trying to control" my friends, I'm just worried that something will happen. Like something unexpected. Hahah I'm probably not making any sense..
