Well, I don't know if it was nice, but it was really pleasant. 

Once I was walking with my beautiful best friend (I always felt myself not so nice as she, because the guys always spoke with her) and a gorgeus guy just stoped, huged me and told "you're so beautiful!" and then just went away. I was a teenager,  so it meant a lot to me. (Then I thought he wanted to steal something from me, but he didn't)

Another time a guy told me that I am a vulcano. I thought it was a nice complement. I still think it now

Oh I understand completely about the "looking young" thing. I'm 39. I look like I'm in my 20's. 

Probably the kindest thing anyone has ever told me, is last year, I was in a cafe ordering some coffee, and the guy said "you have the most beautiful eyes and eyelashes I have ever seen in my life!" I have really long eyelashes naturally and brown eyes, and so I don't wear any makeup. That made my day!

Normally people would say that I look so young which is true. My face looks young plus I have a very petite body which makes me look like a lanky teenager (I'm 24 but look like a 16 year old with my hair up but a little older than that with my hair down) and they would joke around that any boy who would date me would get arrested for child trafficking which I admit it crushed my self-esteem so I was surprised when 2 friends of mine thought I was 22 and asked me if I were already working when they first met me and they were not shocked when I told them that I was 24

It means a lot to me when people think that I look my age or just a little younger than my age because I'm an old soul and I want to be treated professionally/taken seriously 

I hate it when people think that I'm too young to date or work. I don't like it when boys my age or a little older just treat me like a little sister
